HP DesignJet 90 – Part II

Printing

First serious prints and some myths debunked

Let’s get the myths out of the way first. I had read somewhere on the World Wide (disinformation) Web that so much as a sneeze or a hint of moisture would make the inks on prints made with the HP DesignetJet printer run. I had the 8 1/2 ” x 11″ print from yesterday’s evening trial run handy (it was made without any attempt to color balance nor did I use the right paper profile) so I let it dry for one hour and then took it to the Pindelski High Tech Test Lab, also known as the kitchen sink:

My dry elephant seals were now well and truly in their habitat as I soaked the lower half of the print with tap water for thirty seconds. That’s a little more moisture than from a sneeze, I would think. Placing the half wet seals on the Pindelski High Tech Moisture Removal Center, aka the dish drying rack, I let the print air dry overnight and came back in the morning.

Guess what. No color changes or running ink to be seen. Just ’cause it’s written don’t mean it’s so.

As it’s raining today I decided to calibrate the printer and see what she could do on large prints. HP includes 3 sheets each of their Photo and Proofing Gloss, Photo Satin and Photo Matte with the printer in 13″ x 19″ size. Such generosity. I had also taken the precaution of buying 40 sheets of the HP Photo Satin in 18″ x 24″ to try the largest width the DesignJet 90 can handle. That’s a lot larger than 13″ x 19″ – 75% larger.

It has been quite a while since I set up Photoshop to match the Epson 1270 and their Premium Luster paper to make things automatic, so I had quite forgotten how to get through all the arcane menus in Photoshop. Mercifully, HP provides a tutorial CD with the printer (what is happening at Hewlett Packard?), and this one actually loaded first time on the iMac G5, unlike the recalcitrant driver disk. The on-screen tutorial is really outstanding, narrated in clear, non-technical English. The thrust is simply one of “Select these options for the best print” without a lot of gobbledegook about gamuts, color spaces and all that garbage which has little interest to real life photographers who just want their print to come out like it looks on the screen.

I had earlier created a profile for the screen using the Monaco EZColor colorimeter thingy, so I left that alone as the monitor has not been on that long that color drift from age would be an issue.

Unlike the Epson 1270 which is silent when switched on and dormant, the DesignJet has a fan whirring away. Not really obtrusive but a wear part nonetheless, so I switched it off overnight. Warm up took just over a minute and I gave her a try with one of the free 13″ x 19″ sheets of HP Photo Satin whose sheen is identical, to my eye, to Epson Premium Luster though the weight of the paper seems quite a bit more. The back of the HP paper is rough rather than smooth, but I can’t see that mattering either way.

I set up Photoshop as instructed on the CD video and saved the setting as ‘HP Photo Satin’. I haven’t tried the other papers but the HP Photo Matte looks interesting. It is dead matte, lighter in weight than either the Gloss or Satin and very much whiter viewed in daylight. HP recommends it for black and white printing which seems to make sense and indeed their web site has a ton of paper profiles together with very detailed instructions on how to get the best monochrome prints from the DesignJet. Nice to know but right now the focus is color, so that will have to wait.

Clearly, HP has done a great deal of work on color matching and paper profiles as you would expect from a company that has long had a leading position in large format printing in the graphics design and architectural work places.

The Epson 1270 is a very quiet printer. I always had to use it in non-bidirectional printing mode to avoid tracks on large prints, so that doubled printing time and, as I recall, a 13″ x 19″ would take some 28 minutes to make. The DesignJet is a different kettle of fish. It clanks, whirrs and grinds a lot when starting up and then gives a distinctive ‘clack’ with every pass of the print head on 13″ and wider prints, although once running on smaller prints it’s near silent. The table on which it sits has a space frame base construction – light but extremely strong – yet I could clearly see the table vibrate gently with each pass of the print head. To cut a long story short, the print emerged in 9 1/2 minutes and I let it dry an hour before comparing it to the screen in natural daylight. It was immediately clear that print quality was exceptional, indistinguishable from the Epson, and there was no sign of any ink tracks on the surface. The printed area had a 1/4″ margin on the top, bottom and left side and a 7/16″ margin on the right, making for a print size of 12 1/2″ x 18 5/16″, a tad larger than that from the Epson 1270.

One thing I do not like is that you have to adjust the input and output trays in disparate ways depending on the size of the paper, so I’m going to make a little guide for the commonly used sizes and paste it to the top of the printer. HP provides a good guide in their book, but it’s more detailed than I need and involves too much hunting for the right settings.

After the print had dried for an hour I compared it with the image on the iMac’s screen, which is some 14″ wide and I must say it was very, very close. Greens in this landscape subject were a tad darker in the print but everything else was in order. The next test will be with a portrait, whose flesh tones should really provide for critical evaluation. That one will be 18″ x 24″.

Printing

The monster printer arrives

I dropped off the Epson 1270 printer at the UPS Store early in the afternoon not, it should be added, without a sigh. This great machine had served me well and many fine prints testify to its reliability and quality. I think the recipient will do great things with it. If nothing else, it will be a huge test of his technical skill – a 13″ x 19″ is not like making an 8″ x 10″. No sooner had I arrived home than Marty Paris, great acoustical guitarist that he is, arrived at the gate. “I have a big box for you” he intoned dramatically. Gulp! I had been without a printer for all of 45 minutes. Marty is our UPS man in his spare time and you could not meet a finer person.

Well, after Bert the Border Terrier had jumped in the UPS van for his cookie (Marty comes prepared) we struggled to get the 75 pound box on the dolly and lowered it gently to the ground. “Six years I got from the old printer, Marty”. “Wow! Nothing lasts more than three years today. That’s fantastic!” Nice to know the Epson has gone to a good home.

Bertie supervised while I struggled to unpack this bear. The fine people at B&H in New York had not chintzed on the packing, double boxing with more polystyrene peanuts than you really want to know about. By the time I got through the layers of tape, cardboard, polystyrene and plastic, the thing was almost manageable. The weight had halved. I had taken the precaution of clearing a space for it in the office – the old niche was too small – as well as running a long USB cable to feed it pictures. Enough time in the dark recesses of the wiring cabinet, replete with black beetles and cobwebs. There is a fortune waiting for the person who works out how to unwire home computers.

Now I must admit to some dismay on first extricating this monster from its cocoon. When I was an engineering student in London everyone knew that the finest laboratory instruments were made by Hewlett Packard. Later, on Wall Street, a like recognition played into the adoption of the HP12C as the calculator of choice. In neither case were clear instructions expected or available. You see, these devices were made by engineers for engineers, and no real engineer is going to read the instruction book. Heck, when Apollo was landing on the moon, did Buzz Aldrin check the book to determine why the panel was on the blink? Not a bit of it. A solid thump with a fist resolved the issue. It may have been “One small step for man” but a good bang ensured it was “A giant leap for humanity”. Or something.

So the cause of my dismay was none other than some of the clearest instructions known to man, on huge paper that even I could read. I’m not sure whether this means you should buy HP stock or sell it….

Anyway, with psychological support from Bertram, I manhandled the thing onto that nice little oak toppped sofaback I had made many moons ago from some alder, which I ebonized, and some gorgeous stairing oak for the top. It wasn’t conceived as a printer stand, but it does the job nicely.

HP does not supply a USB cable (how cheap is that?) but I was prepared, and my long cable was in place. The mechanical part of the installation was a breeze. You pop in six ink cartridges, followed by six print heads. Not for the colorblind, as several are like-sized, but easy to do.

Then came the software part. Now after my dismay at the clarity of the instructions, not to mention growing concern over the ease of the mechanical setup, I finally ran into a snag. And it was a big one. Try as it might, the drive mechanism in the iMac G5 refused to read the provided software CD. OK, I’m up to it, I can handle this, I’m not panicking. Dial up the HP web site, of course. Just download the driver. Not so easy, pal. The driver’s there, but you cannot download it. Mail order only. Can you believe this? Is Carly Fiorina still in charge, dammit? I though they fired her with a $40mm handshake. OK, OK. I’ll try HP Canada. No Designjet 90 in sight. Fine, how about England then. That bastion of civilization and decency must have the driver, no? No.

What to do? Well, maybe it’s just a quirk of the G5’s drive, or of the HP drive that made the CD. So I pop the CD in the iBook and Hey Presto!, she fires right up. Advised by Bert, that fount of wisdom, I plugged in one of the Firewire external drives to the iBook and before you could say ‘Woof!’ the software was on the G5’s hard drive. Minutes later the printer was installed. No lockups. The only Windows you will find in the old estate are in the walls.

That’s not to say that HP doen’t have some humorists at Software Central. Take a look at their wonderful proofreading of their software installation intructions:

The letter ‘u’ somehow dropped off the HP typewriter.

By this time the sun is setting, the evening libation beckons and I only have time for one quick print from the wretched Photoshop to see if the printer is speaking to the G5. So I load up a RAW image of the elephant seals just north of Hearst Castle on the magnificent Pacific coast and …. a jam. A piercing noise emanates from the beast and the yellow light blinks. Now in case you think HP is no longer dominated by engineers, just take a look at the control panel on this machine:

Now do you see why Aldrin resorted to brute force? Same guy designed the bloody buttons in the Lunar Module, for God’s sake. To be honest I had loaded one sheet of Epson Premium Luster in the HP to try things out, so maybe this was some sort of corporate rivalry at work and HP had the thing jam by design anytime non-HP paper was inserted. So I pressed every button in sight, threatened Bert with physical violence, and slammed ten more sheet of Epson’s finest on top of the one I had loaded.

And she printed just fine. 105 seconds for an 8″ x 10″ which is about four times faster than that great Epson 1270. Colors were right, density a tad pale, but this may well be the start of a beautiful friendship. Even if the birth was a Caesarean.

Long thoughts

Photography, Technique

200mm and 400mm are great focal lengths for landscapes

I have always enjoyed using a lens around 200mm for landscape photography. On the one hand, it’s relatively easy to hold steady hand held or with the aid of a monopod. On the other, it affords the easy opportunity of focusing on the essentials, cutting clutter.

I often find that selecting an elevated viewpoint and then composing to cut out the sky works well. This approach heightens the sense of drama and ‘stacking’ inherent in a lens of this length, such as in this picture taken the other day of some local vines just before spring pruning:

Another example of an elevated viewpoint, looking down into the valley in afternoon light is this one:

And finally, a strongly receding subject like this is only made bolder by the long lens:

Go longer, meaning 400mm in my case, and things get shakier. Literally. There’s more bulk to manhandle and more lens length for the wind to bear upon. It’s not that my 400mm lens is bad – it is not – but I have very rarely managed sharp large prints from it using film as they were nearly always plagued by definition-robbing camera shake. 400mm is long! The new ‘film speed’ opportunities offered by the full frame sensor in the Canon EOS 5D, even at 1600 ISO it’s near noise free, have literally brought my old Leitz 400mm f/6.8 Telyt back to life, once it was suitably adapted for use on the Canon body. This was taken at 1600 ISO and I think the shutter speed the camera selected was 1/1000th. Hand held with no support, the original is wonderfully detailed:

Now while there may be an ‘auto everything’ Canon 200mm L lens in my future, it’s really a pleasure to see these old Leitz 200mm and 400mm warhorses getting a new lease of life.

Breaking up

Photography, Technique

35mm film just does not cut it for big prints.

I finally finished framing the last of the fifteen photographs for the walls of the home theater – a converted garage, I should add, lest you think I have hit the jackpot. A large room, some 700 square feet, it offers lots of wall space even after the big screen installation. All of these are 13” x 19” ink jet dye prints made on the fine Espon 1270, with the delays in framing resulting solely from the incompetence of the local art store (Michaels) which stated they could not get me more 22” or 28” frame pieces because it’s a popular size. No kidding. So I finally ordered the remaining ones from Documounts, an estimable business that wanted my money and charged half as much. They also provided all the mats and boards for the pictures and a local glazier cut the glass to fit. All told, a 22” x 28” mounted, matted and framed print, with a nice ebonized ash frame, ran some $60, or one third of the amount charged by the main street framing place.

So there I was last night wondering which movie to watch, while debating the day’s events with that vicious guard dog and breed standard, Bert the Border Terrier, seen above. The goal of the picture project, I reminded Bertram, was that all the snaps must have been taken within the last twelve months. No recycled inventory of past successes. Change or die. And, in the event, every last one of these snaps was taken within a few miles of our home in central coastal California. There are traditional landscapes, strange surreal beach scenes, and the occasional peeling old wall sign. Acting as tour guide for Bertie, whose attention was enhanced by the promise of a cookie, I recited the story of each for him.

By the by, I found myself thinking about the equipment used to take these pictures. First, the realization dawned that almost every last piece of ‘front end’ gear used has now been sold, given the compelling advantages of the full frame sensor in the digital Canon EOS 5D at these print sizes. Second, of the fifteen pictures, eight were taken on medium format, six on large format (4” x 5”) and just one on 35mm.

Now it wasn’t planned that way. What ended up on the walls had to have visual merit, but it also had to be critically sharp. The reason is that viewers do not respect the rule book that says you should step back when looking at a large photograph. Not a bit of it. The larger the picture, the closer they seem to want to get. Now each of these film originals had been accorded the highest quality processing. The negatives were correctly exposed, film was developed by a great pro lab in Santa Barbara (one of the few that does not play a game of soccer on the beach with your wet negatives) and the originals had been scanned on the highest quality dedicated scanners at 2400 dpi (large format) to 4000 dpi (medium format and 35mm). No grain or dirt reduction software was used to preserve definition. These technologies may be smart, but there’s a trade off. Post processing was done on my iMac G5 whose screen has been colorimetrically (or whatever you call it) balanced using a Monaco EZ Color Optix thingummyjig. You know, the puck you dangle on your screen to measure colors while mumbling incantations to various deities. Bottom line? Color on the screen matches color on the print.

The result is that you cannot tell the large format prints from the medium format ones, but you most certainly can tell the one done on 35mm. Not that there’s anything wrong with the definition in the latter. Using a well calibrated Leica M2 and a 35mm Asph Summicron, that original had, without a doubt, the benefit of the best performing camera/lens combination ever. The Summicron lens is simply breathtaking in its ability to resolve fine detail with great contrast. No, it’s the film that damns the print. You see, if you adopt the ‘stick your nose in the print’ viewing method, the 35mm original clearly shows the film beginning to break up at this print size. There is a hint of grain and, in landscape pictures with much fine filigree detail, that’s a no-no.

Which leads to the inevitable conclusion that for large prints, which are my goal, abandoning 35mm was the right thing to do. Up to 8” x 10”, decent technique and a top class scanner, meaning a dedicated film scanner not some cheesy flatbed, will get you fine prints from 35mm. Anything larger, forget it. Or, if you like the 35mm format with all its advantages of lens choices and compactness, well, Canon has a digital camera for you. By comparison with 35mm film, the full frame digital prints I have made recently are simply night and day when it comes to resolution and detail, and my technique remains unchanged.

The only way around this issue for ‘35mm film only’ photographers is to make sure you don’t show your work head to head with medium format or full frame digital. If you do, all your protestations about making great big prints from a small negative will be so much dross. If, on the other hand, your goal is display on a computer monitor, well, a Holga will do.

Speaking of which, if you like Holga-sized pictures, you can view the ones in my home theater here.

The Epson 1270 printer

When it first appeared on the market six years ago, the Epson 1270 color dye ink jet printer was the first consumer priced printer which could make large – meaning 13” wide and up to 44” long – prints with high quality and repeatability. I bought mine new in March, 2000 for $539.05 and proceeded to produce hundreds of color and monochrome prints with it. First in 8” x 10”, later in 13” x 19” sizes, which makes for a nice 22” x 28” wall sized matted, framed result.

I’m not writing this because the Epson has given up the ghost. Far from it. The only reason that I know exactly when I bought it and how much I paid is that I just resurrected the original shipping box from the attic and found the sales invoice in there. You see, the Epson will soon be making its way east to my nerdy friend whose current printer is limited to 8” x 10”, and he know and loves the quality this machine is capable of, reliably producing at 13” x 19” prints.

Ink remains easily available, even if all the colors are in one cartridge and the Epson’s software is about as good at predicting the ink levels as the Federal Reserve is at predicting inflation. Which is to say it gets it in the ball park but don’t stake your life (or next print) on it. Epson sold a lot of these wonderful printers and given the profit margins on ink sales you can bet fresh ink cartridges will be available for a long time.

Conservatively, I’m guessing that the 1270 has at least another four good years left in it, which makes for a ten year life in a digital age where products are seemingly obsolete days after hitting the market. Epson made the 1270 obsolete soon after I bought mine and eventually switched to pigment based inks with claims of great longevity. Didn’t worry me one bit. I have framed originals which are six years old and they look as fresh as the day they were made. I simply do not display them in full daylight eight hours a day.

One of the great appeals of the Epson 1270 was that its use of dye based inks, despite their reputation for fading, resulted in a color print quality very similar to that obtained with the old Cibachrome process. This was, for most, not something to be undertaken at home, as the temperature margins of the chemicals were narrow to put it mildly and their toxicity comparable to the effluent from Chernobyl. What Cibachrome gave you was a wonderful depth of color albeit at the expense of high contrast, so it matched up nicely with milder emulsions like Kodachrome II and, later, Kodachrome 25 and 64, provided your exposure was spot on. Paired with that old grain hound GAF/Ansco 500, Cibachrome was a dream. It was a strict teacher, but get the exposure right and the dynamic range was there for all to see.

The only reason the 1270 is moving on is that I find I want to make 16” x 20” and 18” x 24” prints more often, and if that does not sound like much of a change the latter size is almost twice the area of 13” x 19”. That’s a lot bigger when it comes to visual impact.

So B&H Photo has an order from me for a Hewlett Packard DesignJet 90 (they are backlogged, suggesting the secret is out) offering dye based inks which, miracle of miracles, are allegedly fade resistant. I toyed with the idea of the Design Jet 130 model which goes up to 24” wide, but concluded that prints that large were pretty much the exception rather than the rule for me, so common sense prevailed over machismo.

Truth be told, I am a tad apprehensive about the new printer. Not that installing the thing worries me – heck, with an Apple iMac it’s just one more ‘Plug and Play’ exercise. No, as a long time user of HP’s 12C calculator (a device now some 25 years old!) my wariness results from my all too great familiarity with HP’s instruction manuals. Hewlett Packard was always an engineer’s company, run by and for engineers, with the brief exception of a disastrous, mercifully brief, time under a chief executive who confused her posterior with her elbow daily, while spending far too much time on the former in the corporate jet. Now that the company has returned as an engineering powerhouse, I’m afraid that the same people who wrote the manual for my 12C calculator will have been involved in the book for the DesignJet. They or their kids.

On the other hand, like all good engineers, they probably believe that instructions are for losers, so the first thing I propose to do when the machine finally arrives is to pitch the instruction book. Worked with the HP 12C and Reverse Polish Notation was never an issue for this Pole. Any descendant of a proud nation that can charge Panzers on horseback needs no instruction book. And it doesn’t hurt that I have an honors degree in Engineering earned before the days of ‘open book’ exams.

Goodbye Epson. You delivered beyond any rational expectations.
