Description

This group supports the Quadtone RIP written by Roy Harrington and QTRgui written by Stephen Billard. QuadtoneRIP runs on both Macs and PCs. QTRgui is available only for the PC. Posts to this list should relate to the use of these programs - typically for black and white printing of digital images. For more general discussion related to black and white printing visit the Yahoo group DigitBlackandWhitethePrint.

If you are a new member, note that your posts are moderated. That means it may take a while for your posts to be processed by the list because they have to be vetted by a moderator first. That can take a while, sometimes hours, so be patient. Once we've seen a few posts and are satisfied you're not a spammer we'll take you off moderation. If you feel your messages have been moderated (and delayed) for far too long, let me know. You can reach me at
QuadtoneRIP-owner@yahoogroups.com

The group philosophy and guidelines regarding posts are as follows:

  1. Posts should exhibit a gracious tone.
  2. All rants, flames, obscenities, politics, religion, "global warming" etc. will be ruthlessly deleted and their authors banned.
  3. Posts should NOT just be of interest to a known few; use an email. As much as I enjoy "thank yous" in the rare case where I am helpful, an email will save the rest of the group from boredom. Applies to my idiocies too.
  4. When looking for help, provide DETAIL; not just "it doesn't work". Let us know what environment - Mac or PC? OS? what printer/paper/ink? what you did? what actually happened? Providing all the details at the start will generate more responses and require fewer clarifying questions - saving everyone time and energy.

Am I ever wrong about moderating? Of course. Send me an email. I'm open to suggestions.

Tom Moore (Group owner and moderator)

Re: Help calculating ideal Lab L values
I suggest you use the 21 x4 chart... measuring 256 is not going to get you a smoother curve. The random 21x4 works well...this is what Roy suggested...

Re: Printing over network
this worked perfectly Roy. The somewhat finnicky TCP/IP ports still worked right off the bat on the PC, and the printers connected to the switcher immediately
