Great Article on How to Solve a Recent Color Management Issue

I just read an article by Mark Dubovoy covering a recent issue with printing targets for custom profiles using Apple Snow Leopard (10.6), Epson drivers and Apple Computers on Luminous-landscape.com. I’ve delayed my official update to Snow Leopard because I usually like to wait a few months to upgrade after initial testing. I’ll be testing this approach with Epson and other drivers soon.

You can find the article here with a step-by-step workaround to fix the problem:

Inkjet FAQ 003: How can I easily test my lab’s print output?

This is a common question, and I have a pretty simple answer. First, it is important to have a calibrated and profiled monitor (a.k.a. display). Without going too far into that topic, the next step I recommend is to use a “target,” or test image, as a benchmark to help determine whether your monitor is displaying images properly. By printing out the target on different days and possibly on different papers, such as gloss, luster and metallic, you’ll be able to compare them side-by-side. You’ll also see whether there are significant changes from day to day.

The following 4×6-inch test file can be downloaded at the link below:

The file contains color and black and white images sized to 280PPI on a 4×6 canvas and saved with the sRGB working space.

You should then save the file as a JPG file (quality 9, 10, 11 or 12 is recommended-12 is best, but will create a larger file) and send the target image to your lab to print.

Because this tip is primarily for continuous-tone printers like those found in professional photo labs, the file is in the sRGB working space and Photoshop PSD format. Saving a JPG on top of a JPG is a no-no because you will keep introducing more artifacts as you save a JPG on top of a JPG. The image includes some text, which also helps to judge the sharpness of the lab’s output.

Note: It is very important to instruct your lab to turn off any color correction, or you won’t be able to properly control the color and density of your prints!

I have a similar file here with the same test image in AdobeRGB color space, which is ideal for inkjet printer testing.

Enjoy!

Full-Day Inkjet Printing Workshops 9/12 and 9/13

I posted information on the InkjetTips.com and ImagingBuffet.com workshop pages a few weeks ago about two upcoming full-day workshops that I’m conducting in New Brunswick, NJ at Alfa Art Gallery on Saturday, September 12 and Sunday, September 13. Some seats still remain for both workshops, which are limited to just 8 participants each. I currently have a show on exhibit at the gallery entitled East + West, featuring photographs of New York and Japan. Having the workshop at the gallery allows me to describe the prints up close, and properly lit under gallery spotlights.

The fee for either full-day workshop is just $179. I’d also like to offer a $30 discount on either of the two workshops to our readers, which is valid if you register by Thursday, 9/10.

For more information or to register for the Saturday 9/12 workshop (the discount code is embedded), visit this page.

For more information or to register for the Sunday 9/13 workshop (the discount code is embedded), visit this page.

For either day, the page will display “sold out” at the top if all 8 seats have been reserved.

All the best!

Upcoming Color Management and Inkjet Printing Workshops in NJ

I’m very happy to announce that I’m conducting two color management/fine-art printing workshops on January 31, 2009 at a new pro rental/fine-art reproduction studio located in Hillsborough, NJ (near Princeton). One runs from 10am-3pm and the other from 4pm-7pm.

For more information or to register, visit this page. I hope to see some inkjettips.com readers there!

Inkjet FAQ002: Finding Output (Paper) Profiles in Mac OSX

Inkjet FAQ 002: I can’t find my Canon, Epson or HP profiles in my Profiles folder, but I see them in the Photoshop Profiles dropdown list under File>Print, and when I choose “Other” in the Color Management section in Lightroom’s Print Module. Why oh why???

When you install a printer driver from a CD, or by downloading it from the printer manufacturer’s website to make sure it is a current version (recommended), printer profiles are generally a part of the install. For Mac users using OSX, the profiles will usually be placed in one of three places:

1. /Library/ColorSync/Profiles (visible and usable by all users).

2. In your User folder (next to the house icon)/Library/ColorSync/Profiles (visible and usable by just the current User).

or here:

3. Main Hard Drive with your OSX system files/Library/Printers

What’s interesting is that OSX Spotlight searches for the profiles in Number 3 above don’t appear to work (at least they didn’t for me). Files in that section may be considered special files, and I’m sure a Unix/OSX systems expert will know exactly why that’s happening.

Also note that you will need to restart Photoshop (or any other color management aware application from which you are printing) if Photoshop is open when you add profiles to your Profiles folder. That will allow the profile list in Photoshop to refresh.

A more efficient way to find all the profiles on your system is by using a great application that comes free with your Mac. It is called “ColorSync Utility” and can be found in your Applications/Utilities folder.

One section of the Apple ColorSync Utility with the “Profiles” icon selected.

After launching the application, choose “Profiles” from the icons at the top of the screen, and then look down the list on the left of the screen. If you look inside the item named “Other” you will see the path to the “hidden profiles” that I mentioned in Number 3 above. You can also take a look at the profile in 3D color space.
