Epson P800 QTR digital negative starting point
2016-07-27 by philbond87@...
Does anyone have a basic starting point for a P800?
Would starting with a profile for a 3880 – and modifying it based on output – be a reasonable way to proceed?
Thanks!

Inks are very different. Depends on your experience and abilities with photoshop and printing. I started here: https://jkschreiber.wordpress.com/platinumpalladium-notes/digital-negatives-with-quadtonerip/ded <https://jkschreiber.wordpress.com/platinumpalladium-notes/digital-negatives-with-quadtonerip/ded> Decided then I could not take the time or had enough experience. I decided to take a class with Kerik Kourik which was one of the best decisions I made. He is a wonderful person and teacher. -Felix Martin www.felixm.com <http://www.felixm.com/>

Felix,
I totally agree – Kerik is definitely one of the best... a really great guy and the person who inspired me to pursue PtPd to begin with. I'm actually hoping to do a one-on-one with him later this year.

Hi Phil, I’ve been working on profiles with an artist who is printing Pt/Pd on a variety of tricky Japanese papers and was looking to improve her digital negs. She was trying to make profiles using a scanner to read the values and having all sorts of problems. Someone referred her to me for help. She had a 3880 when we started but it suffered a catastrophic failure midway through the profiling process. She replaced it with a P800. We started from the beginning again with the 3880 base profile, made a couple of minor adjustments, and ended up with a good base profile for the P800. I am happy to share it with you. It is for the P800 with the stock Epson inks. You will have to print with it, analyze the results (preferably with a spectro or densitometer), and create your own Gray Curve for your specific paper and chemistry. Copy and paste into a text file, change the notes to reflect your details, and change the curve name to something that is meaningful to you. The main difference between this and my 3880 base profile is the Gray Gamma setting. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #Notes Profile for Pd 2.5% Na2 AC ~75F on Shikibu Gampi PRINTER=QuadP800 CURVE_NAME=MV_P800PK-UPOHP-Pd-AC-ShikibuGampi GRAPH_CURVE=YES N_OF_INKS=8 DEFAULT_INK_LIMIT=60 BOOST_K=60 LIMIT_K=60 LIMIT_C=5 LIMIT_M=5 LIMIT_Y=12 LIMIT_LC=5 LIMIT_LM=5 LIMIT_LK=60 LIMIT_LLK=80 N_OF_GRAY_PARTS=3 GRAY_INK_1=K GRAY_VAL_1=100 GRAY_INK_2=LK GRAY_VAL_2=40 GRAY_INK_3=LLK GRAY_VAL_3=10 GRAY_HIGHLIGHT=2 GRAY_SHADOW=6 GRAY_OVERLAP= GRAY_GAMMA=0.8 GRAY_CURVE="0;0 100;100" N_OF_UNUSED=0 COPY_CURVE_C=K COPY_CURVE_M=K COPY_CURVE_Y=K COPY_CURVE_LC=LK COPY_CURVE_LM=LK ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Feel free to contact me directly if you’d like.

Hi Keith, By any chance have you had any experience using the P800 and other papers? -Felix Martin

Hi Felix, I haven’t used it myself. Only indirectly via this artist and then only the Pt/Pd 21-step tests that she is sending me to read and profile. I don’t really do much inkjet printing on paper except for proofs before making negatives. I am very disappointed that Epson chose to eliminate the rear manual feed on the P800 though. Personally, I’ve switched to using PiezoDN for digital negatives, initially on a 1430, and soon on a 3880. I was intending to use it on a 4880 but that machine suffered an electrical problem a few weeks ago that I have been unable to fix. Walker Blackwell at IJM says that there is a dithering issue (or something like that) with the P800 and PiezoDN that they have not resolved yet, so I decided to get a 3880 refurb to replace the 4880. I don’t have room for anything bigger, and the 1430 doesn’t handle the panoramic format that I am working in very well. Cheers, Keith "Ever tried. Ever failed. No matter. Try Again. Fail again. Fail better." ~ Samuel Beckett

Felix,
I'd be glad to connect with you offline and update you on my progress. Your email, however – at least on my iPad – seems to have been truncated.
In short, although I've not had much time to devote to it over the past couple of days, I have made some progress. So far I've taken Keith's base profile and have been iteratively modifying it for my process. Hopefully this weekend I'll have a good gray curve to apply to it. (It might have to wait for more Pd to arrive though!)
