Unsharp Mask Demystified
Thursday September 9, 2004
by Ellen Anon

"Ask any number of digital photographers the settings they use in Photoshop’s Unsharp Mask filter (USM) to sharpen their images and that’s the number of different responses you are likely to get. Because of this a significant number of people turn to plug-ins to do their sharpening for them. However once you understand the basic principles involved in using the USM it is fairly easy to make it work predictably and effectively."

ImagePrint 6 Notes
Thursday September 2, 2004
by Mitch Alland

I am pleased to see that the new ImagePrint manual for v6 is a great improvement over earlier versions and is, in fact, excellent. The extensive Troubleshooting Guide section is a good addition. Also, as program installation has been simplified, I believe that most questions on IP problems that come up on online forums can now be answered by suggesting, in the best Unix tradition, that the user "look it up in the manual...." These notes are based on ImagePrint 6 build 1.08. If you are using a later build some of the issues and glitches discussed below may have been fixed, as ColorByte is aware of all of them.

AuthorSubject: Getting a good gray ramp?   [Go to Bottom of Page]
JAMES B RESWICK JR
Posted on Fri Jan 2, 2004 11:18 PM

Hi:

I no sooner posted this in the hardware forum, when I realized that it should have been here. Probably the same people read both, but anyway...


What is the recommended workflow for fine tuning the gray ramp in profiles?

Twiddling with the profile editor? Twiddling with the Black Generation during profile creation? Twiddling with the ink restrictions in the RIP? Or...?

I can get a pretty decent K ramp out of the printer with just the RIP, but the gray ramp running out of the profile starts to show cyan and then magenta at about *)% gray, and then black suddenly comes in strong.

With CMY, do I have to ensure that the CMY ramp is pretty neutral before I even print the profiling target? (It is consistently too green, but I haven't woried about it, as I have tried to set restrictions and linearize for maximum ink for each channel, rather than gray balance.)

I've played a bit with different black generation and total ink, but can't get things smoothed out. (Otherwise, the color seems to be good)

I know that this is a traditional problem, but any help would be appreciated...

The lineup:

Epson 9600, Ultrachrome Matte Black, Hahnemuhle Photo Rag
Onyx RIP in WIN2K
Monaco Profiler in WIN2K (using largest target), default Relative Colormetric
EyeOne
Link-O-Lator in OS-X using black point compensation
iQueue in WIN2K using DeviceLink profile


Thanks,

Jim
