Examining the different wedges, I picked the best 2, that showed a 0 level very close to 0 (in both cases K=8-9% that seems to be the whitest I have ever achieved). txt files with these permutations, installed them all, and printed a sheet. Then I used a single Pictorico sheet and printed seven 21-step wedges with slight variations around these, and did the carbon print. In short, - The first step started with the 8-ink separation run, and from it, determined a LIMIT_K=20, LIMIT_Y=25 and LIMIT_LK=50. Hi Sandy, OK, after several iterations I think I'm getting close. The Carbon 100 and 200 profiles I describe in the files do not take the level of difficulty out of the learning process, but they work well as similar profiles are used by quite a number of carbon printers. Learning the process of carbon requires time, so to does learning to craft digital negatives. You would want to use this document in conjunction with the doc and text files in the folder QTR Profiles for Carbon Printing as these have all been updated since the draft of the chapter in the book was written. The book is not currently being sold, and would likely be revised if publication is resumed, so I am making this document available to you and anyone else who may be looking for a good explanation of the process but not willing to invest in Carbon Transfer. It is an early version of a chapter on digital negatives that was co-authored by me and John Lockhart, and published as an ebook in 2016. There is a very thorough discussion of digital negatives in the book on carbon transfer that was published last year by Routledge Press, co-authored with Don Nelson and John Lockhart. I have attached a document file in a folder in this forum called Digital Negatives with QTR. Dan, If you have an Epson 3880 in good working condition that passes the nozzle check you are ready to make very good negatives with QTR.
