Dear Jon,<\/p>\n

Found your website and information from Boxcar Press and would like to discuss a few art things with you. I talked with my friend Patricia Brandstead this morning and she said you are a good resource for someone learning polymer photogravure.<\/p>\n

A little bit of background: I have been a printmaker for 30+ years starting in Honolulu and have been making copperplate photogravures for 25+ years both in Hawaii and Colorado. This spring, returning to Hawaii and meeting up with printmakers there, I was kindly shown how to make polymer photogravures as an alternative to copper. I returned with 5 lovely etched plates! My studio is in Steamboat Springs (where Oehme Graphics is) and I have a small Brand press and a NuArc NL22-8C exposure unit. I am able (usually) to make transparencies in my Epson printer with PictoricoOHP film and I have a great screen from Mark Nelson. More “equipment” is ordered.<\/p>\n

I have a feel for the basic “flow” of the process but have a few sticky challenges:<\/p>\n

1. my exposure unit is a glass-topped vacuum frame which I think needs to be modified, with Kreen film?, to work with the polymer KM73 plates. Don’t have a clue how to do that<\/p>\n

2. cutting the plates seems to be a challenge so I’m going up to Oehme Graphics to attempt to use their plate cutter<\/p>\n

3. I have no idea of exposure units except for the times I use for copper and figuring out the curves etc are way beyond me. I have the transparencies made (by a friend) to compare to the ones I use for copper<\/p>\n

Do you give workshops?
\nDoes anyone?<\/p>\n

I’ve downloaded your instructions from your site — they’re great. Would appreciate feedback as I’m feeling the polymer plates are even better than the copper!<\/p>\n

Sincerely,
\nBarbara Sanders<\/p>\n

Hi Barbara,<\/p>\n

Thanks for your message.\u00a0 Ironically I “pocket called” Patricia this morning by accident!\u00a0 Polymer has some challenges, but what doesn’t?\u00a0 It is a rewarding medium, but it did take some time to get happy with it, or it with me.\u00a0 \ud83d\ude42<\/p>\n

I removed the glass from my vacuum frame years ago to prevent newton rings which Harold Kyle at Boxcar advised me on, and I never looked back.\u00a0\u00a0 If you don’t have issues with newton rings, no need to even do it.\u00a0 My online procedure outlines what has worked for me and my process. Yours may be different. Since that time Pictorico has released a textured OHP media which may prevent newton rings.\u00a0 It also supposedly eliminates the need for baby powder which I used to prevent contact problems between the plate and the OHP, which tends to be a little tacky.\u00a0 I’ve never used it, but you might try it before going through the pain of dismantling your vacuum frame and removing the glass.<\/p>\n

I’m using a custom aquatint screen that is considerably finer than those commercially available, among which, Mark Nelson’s are probably the best for polymer photogravure using the Toyobo KM73 plates.\u00a0 He also gives workshops a few times a year that are quite popular and well received.\u00a0 He has a special process for creating digital negatives and curves using colored inks on Epson printers that is rather involved but yields good results.\u00a0 I was never able to get it to work for me, but it could be because my aquatint screen is finer, which is a double-edged sword.\u00a0 Greater tonal range, but more pressure and contact is required in both the printing and creation of the plates.<\/p>\n

I use a large, Kutrimmer, floor model paper cutter to cut and trim out plates.\u00a0 You want something sturdy, sharp, and tightly assembled.\u00a0 Wobbly ones ruin plates and patience!<\/p>\n

Exposure times will be custom to your exposure unit and media used.\u00a0 My exposure times will likely be different from yours.\u00a0 Same with curves.\u00a0 Your inkjet printer will differ from mine such that, even if we have the exact same models, the output will differ.\u00a0 Determining the right curve to use is an iterative process — lots of trial and error as with most things printmaking and you’ll want some basic training in Photoshop to become familiar with using curves as an Adjustment Layer.\u00a0 Lynda.com has some great Photoshop tutorials.<\/p>\n

If you’re consistent in your test process, you will get where you want to be with it eventually.\u00a0 I don’t give workshops, but I do make plates for printmakers, and give private consultations through my company Intaglio Editions: http:\/\/intaglioeditions.com\u00a0 I’m also happy to share whatever information might be helpful to you in your pursuit of the process.\u00a0 If you’d like to do a private consultation on the process either over the phone or in person, at your studio or mine.\u00a0 It seems pricey I know, until you compare it to the thousands of dollars in time, plates and paper I’ve blown over the years!\u00a0 Call me if you want to discuss it or have any other questions.<\/p>\n

Also, would it be OK with you if I were to reprint your questions and my answer on my website?\u00a0 I’ve found it helps people get answers they need more easily sometimes.<\/p>\n

Kind regards,
\nJon Lybrook<\/p>\n","protected":false},"excerpt":{"rendered":"
