Printing with an emphasis on the HP DesignJet dye printer

HP DJ90 with Snow Leopard

Phew!

Long time readers will know that I use a Hewlett Packard DesignJet 90 to make large prints using my iMac. I suggested it made little sense to rush into the OS 10.6 upgrade (Snow Leopard) until many of the incompatibility issues were resolved. Indeed, Snow Leopard has already had one upgrade to address security issues since I wrote that piece.

Well, some good news. HP has released new printer drivers for the DJ 30/90/130 series (respectively 13″, 18″ and 24″ wide) as stated in this Apple Support document. This is great news for those of us using what may be one of the best ink dye printers made. While recently discontinued, I confess prints made with it today look every bit as good as they ever did! My only grumbles have been the occasional blocked printer head, easily replaced. Click ‘Printing‘ on the right for more about this outstanding piece of hardware for serious sized printing.

Update 1/2016:

There is one more benefit to keeping a Snow Leopard boot drive handy. SL was the last version of OS X to include Rosetta, the emulation software which allows Intel Macs to run PPC (IBM G3/4/5 CPU) apps. This is important if you want to run the HP online System Maintenance Utility which is coded to work with PPC CPUs only. And you really want to be able to run that utility as it is the only definitive way of identifying printhead issue, allowing you to hone in on the faulty head – see Page 3-10 in that linked PDF. See here for details.


Snow Leopard – the last great OS from Apple before the tinkerers took over.

You can still buy Snow Leopard from Apple for $20. This is not altruism or nostalgia on Apple’s part. Rather, SL (10.6) was the first version of OS X (from 10.6.4) to permit access to the AppStore wherefrom all subsequent OS X upgrades are made over the air, Apple no longer shipping OS X on DVDs. So without SL you cannot access the AppStore.

I actually use an old PPC iMac G4 to access HP’s utility but you can do just as well using SL for less trouble.

Going glossy

Just doing what it takes

I have been unsparing in my criticism of Apple’s cynical move to producing only glossy screens on its displays. The thinking is identical to that of the jeweler who installs strong quartz iodine spotlights in his store. That 1 carat bauble that so impressed in the store, thanks to the Hollywood lighting, leads to a sense of dismay when viewed at home. It’s no different for Apple’s glossy screens.

So what on earth was I doing ordering glossy printing paper for my HP DJ90 the other day?


An engineering company. Note the micrometer and the Swiss manufacturer!

Well, I may dislike glossy when it comes to making and printing my photographs, but I am not beyond learning from the ace salesmen at Apple, Inc.

Simply stated, I have not submitted a photo for publication since 1977 when I left England and started getting paid for my labors in America. So great was the increase in income and reduction in tax (the top income tax rate when I left the UK in 1977 was 83% ….) that the modest amounts that publication brought no longer made sense. I could earn more the easy way and use the money to take the pictures I wanted to take, not the ones some editor preferred to see.

But the bug bit again recently and while I have no intent to make any money from getting my stuff in print (and the odds of doing so are, let’s face it, pretty remote in an internet world), my ego can now afford it. And as first impressions are 100% of the battle with photographs, when that editor opens my envelope of snaps I want them to say ‘wow’. Glossy paper does that.

So the medium, not the content, may be the message, but if it ghastly glossy paper helps get me into print, so be it. Just don’t expect these prints to be gracing the walls at home any time soon.

This is my first experience of using HP Premium Glossy. The inked areas are matte whereas highlights where no ink was deposited retain the original high gloss of the paper. However, after drying for a couple of hours the inked areas take on a good gloss, although not as high gloss as virgin paper. So it may explain why some later printers now use a glossing agent to restore high gloss to a print – the DJ90 does not have this technology.

Picture Packages

A useful Lightroom technique

When I make large prints on the HP DJ90 dye printer, it’s usually strictly a ‘one at a time’ sort of thing. The prints are 18″ x 24″ (‘Super A4’ is the uninformative European description), which is as large as my HP will go and, after an obligatory 24 hour ‘drying’ period to let the ink dyes set, they are dry mounted and framed.

However, with my new found determination to get some work published again, smaller prints were called for – 9″ x 12″- and these just happen to divide an 18″ x 24″ sheet into four equal parts.

Rather than cut up the paper first and then do four print runs, it proved just as easy to make one combined print job and do the cutting last.

First I went into the Library module of LR2 then clicked on Library->New Collection. I dragged the candidates into this new collection and oriented them all vertically (Photo->Rotate Left/Right). These candidates had been processed and cropped just so, so that no further adjustments would be required.

Into the Print module of LR2, where I clicked on Tempate Browser->Lightroom Templates->2×2 Cells. Lightroom comes with this template installed. Moving the mouse cursor to the base of the screen to disclose the filmstrip – which I have set to hiding mode so it is ordinarily invisible – I simply highlighted four contiguous images, which then appear on the print ‘canvas’.

The screen now looked like this:

Then it’s off to the races, printing in the usual way. It takes a lot less time to do than to explain and you have the benefit of applying the same print settings to all pictures on the ‘canvas’. Of course if you process the originals poorly, then you may end up with four clunkers, but I seem to have lucked out.

Note the personalized nameplate at the top left of the Lightroom pane in the last picture above. You can do this by going to Lightroom->Identity Plate Setup.

HP Designjet paper profiles in Lightroom 2

Trust HP to design this for engineers, not humans

In yesterday’s column I mentioned the existence of aftermarket profiles for some interesting papers made by the likes of Hahnemühle and Arches. These are swellable papers designed to absorb the ink dyes used in the HP DJ 30/90/130 printers. That’s all well and good, but how on earth do you get these to show up as choices in Lightroom when you are in the Print module? Especially as the instructions from HP for the right place to install these simply do not work.

Well, HP is first and foremost an engineering company which means that things obvious to engineering graduates are gobbledeegook to regular humans. Mercifully, your instructor, Dr. Pindelski, happens to have an engineering degree, so if you use an HP Designjet 30, 90 or 130 printer, follow the instructions below and all will be well …. so long as you have the good sense to get a life and use a Mac. PC users can probably figure things out from what follows, but please do not ask as I neither use nor propose to ever use a PC again.

Here’s the Print module in LR2:

Click on ‘Managed by Printer’ then click ‘Other’ and you get a listing of the standard HP paper profiles:

Now go to Finder and click on the Library (this is the Mac’s library on the root of your internal hard drive, not the one under your name in Users) and navigate to the directory show – navigation is from bottom to top (this is for OS Tiger – see below for the changed location in Snow Leopard):

Your Finder screen now looks like this:

Now Control-Click on the file named ‘hp_designjet_pm.plugin’ then click on ‘Show Package Contents’:

Now drag and drop the downloaded package of profiles (see yesterday’s entry for the download link) onto the directory named ‘ICCProfiles’:

The ‘designjet’ directory is the one with the new profiles, which you just dragged and dropped.

Click on the ‘designjet’ directory in ‘ICCProfiles’ and you will see all the additional profiles, thus:

Snow Leopard update:

Additional paper profiles are stored in your user directory thus:

Location of additional paper profiles in Snow Leopard.

The remaining task is to edit the ICC profiles of your choice so that they will show up in the LR2 drop-down box. The snag is that you have to use one of the tailored HP name strings to force the choice to show. This means two things:

1 – You must use a file name identical to one of the existing ones used by HP for their papers
2 – You will have to embed your profile description of choice in the replacement new paper profile for it to display meaningfully in the LR2 drop-down box.

First, then, we have to determine which of HP’s standard paper choices we can dispense with. That’s easy, because you didn’t buy this fabulous printer to use Brochure or Proofing paper or for that matter generic Coated paper, so that means at least nine of HP’s file names can be reused. Further, if you stick with the ‘Max Detail’ drivers, you get even more redundant file names to use – and why would you want anything but maximum detail in your display prints?

First, determine the new papers for which you would like to install profiles – here’s the list from the file downloaded from HP:

I’m intrigued by the Arches, Hahnemuhle and Ilford papers. so in the following screen snap I have erased those imported profiles which are not wanted and also erased all the clutter from the inclusion of the HP Z2100/Z3100 profiles which are for HP’s latest – and very expensive – wide carriage pigment printer, thus:

As I am adding nine new profiles I will need to reuse nine of HP’s file names to make these show up – here’s the ‘conversion’ table:

To embed these paper names in the new profile ICC files we have to edit the profiles, rename them using HP’s cryptic file naming convention, rename the original files rather than erase them, in case they are needed in future, then move the new files down one level in the directory so that LR2 can read them.

Double-click on the first new file, the one for Arches Infinity Smooth 230 paper. You will see this as Colorsync opens:

Click on ‘Localized description strings’ and enter the name you want for the paper of choice – the default looks like this:

Those names are awful (this is the text which will show up in LR2) so I make them more user friendly, like so:

Now save the file in Colorsync (Command-S) and move on to the next one, repeating as necessary with descriptive names for each paper.

Next we have to rename the original files which are no longer needed; I do this by simply appending the text “.old” to the name of the original file; use the conversion table you created above to determine which files need to have ‘.old’ appended to their names:

Next, rename the new paper profile files using the old HP file names – the same ones where you just added the “.old” extension, like so, repeating for each new profile and making sure to use unique HP file names from the original files, with no duplications:

Here all all the name changes on the new files:

Finally, drag these renamed .icc files down one level to where the “.old” files reside, thus:

Load LR2 and click on Profile->Other in the Print module and this is what you will see:

To further clarify matters, I then add the text “HP” to the HP paper profiles, using Colorsync as before, with the following result – compare with the previous screen snap:

Now check all the boxes thus to make these properly named profiles show up in future when you click in LR2 and hit ‘OK’:

Next time you click profiles in the LR2 Print module you will see this:

Select the profile of your choice, load the appropriate paper in the printer and off you go! But do first make sure your display is profiled properly and, of course, I highly recommend Dr. P’s free screen profiling approach which will not only save you money on the colorimeter you do not need, but will get you more accurate colors to boot.

I took the additional precaution of making the new, renamed .icc files ‘read only’ to make sure that any new profile or application updates do not overwrite the files created above. You can do this by control-clicking the .icc file, clicking on ‘Get Info’ and making it ‘read only’ in the dialog box that pops up.

Why use printer-managed profiles rather than application managed colors? For the simple – and vital – reason that when you hit Print->Preview in LR2, Apple’s Preview application will display a Preview; at the lower left you will see a box for previewing the print on the screen using the color profile you have chosen – so much for all the ‘experts’ who maintain that you cannot soft proof with applied paper profiles in Lightroom:

You are now viewing a Print Preview of your picture with the paper profile of choice applied to the image. And you can use a selection of non-HP branded printing papers. What’s not to like?

And I can think of no better time to buy one of the truly great wide carriage printer bargains – HP still lists the Designjet 90 (18″) for $995 and the Designjet 130 for $1,295 (24″). I would not hesitate to buy another today and do, on rare occasions, rue the fact that I did not buy the 24″ model as the form factor is much the same with six inches added to the width. Either takes up little room for such a large format printer. OK, so they go ‘clankity-clank’ when they print, but you can afford ear plugs from the $2,000 saved on not buying their latest Z series machines. And ink use is so frugal, even a Scot would approve.

Latest ICC color profiles for HP Designjet dye printers

HP updated these recently

While I have been a happy user of HP’s branded papers exclusively for my Designjet 90 18″ wide dye printer, HP does not entirely neglect the aftermarket for paper makers.

Indeed, HP has recently updated a bunch of color profiles for some well known papers which feature the swellable/absorbent surface of HP’s paper, allowing the printer’s dye inks to be properly absorbed. These are for use with the Designjet 30/90/130 series of printers.

Here are the papers supported, with details of how to feed the paper into your printer – tray, rear slot or roll (by the way, I always use the tray to (multi-)sheet feed my 13″ x 19″ and 18″ x 24″ HP Premium Plus Photo Satin paper and have had no issues):

As you can see, HP recommends that many of the heaviest papers are loaded one sheet at a time. For reference, HP’s Premium Plus Photo Satin weighs in at 286 grams/sq. meter, whereas the heaviest William Turner is 310. I suspect, but cannot confirm, that HP’s papers are made by Hahnemühle which has been around since 1584, so they just missed making the stock for Gutenberg’s bible, printed in the 1450s.

Here’s their data sheet on the heavier William Turner paper:

Many stockists carry it, not least of all Atlex which I have found to be reliable. The William Turner comes in sizes up to 17″ x 22″ or in larger rolls – these you would have to cut down first. Sounds like an interesting option for HP users and, as I mentioned recently, I would be a buyer of the HP DJ 90 or 130 (24″ wide) today – it’s not like parts and supplies are about to disappear for a printer which shares consumables with the DJ 30 (13″ wide) which sold in vast numbers to photographers everywhere. And, at its price, the wide carriage HP has no competition.

Finally, why dye based inks in preference to pigments which now dominate the market? Can you say lousy blacks? Bronzing? We dye printer users know nothing of those issues.

In tomorrow’s column I will provide a step-by-step guide to making new profiles of your choice, for non-HP branded papers, display correctly within Lightroom 2 because, goodness knows, HP’s installation instructions are about as wrong as you can get. Suffice it to say that if you follow mine, your profiles will display correctly in LR2 thus:
