New Polymer Photogravure Book

Photogravure Manual by Henrik Boegh

Artist Henrik Boegh of Denmark, author of  Handbook of Non-toxic Intaglio: Acrylic Resists, Photopolymer Film & Solar Plates Etching has just released a must-have handbook that covers many of the basics of his first book for creating supurb plates and prints using the classic Double-exposure method and an aquatint screen. This book is for beginners and slightly more advanced for students with an interest in more advanced Duotone techniques, as well as Direct-to-Plate, or DTP.

Henrik is a veteran author and University professor who has taught printmaking for decades after leaving his post as Chair of the Economomics department at a prestigious university in Copenhagen to pursue his craft of printmaking.

This book cuts to the chase and provides essential guidance for the begining student and excellent set of guidelines and new approaches that may surprise even the most photographically critical printmakers.

Fine Art Paper Tests for Double Exposure, Polymer Photogravure

We recently made a major change to our plate making workflow at Intaglio Editions, and added new quality-control steps for monitoring any changes in plate sensitivity among plate batches.  We also confirmed changes in plate sensitivity occur in Toyobo KM73 plates over time — even when stored in ideal, light-safe conditions.  Thanks for Clay Harmon for bringing this important variable to my attention in his artful book on making Double-Exposure polymer photogravure plates: Polymer Photogravure: A Step by Step Manual Highlighting Artists and their Creative Practices

This change in workflow includes employing a new method of deriving our process compensation adjustments using the Easy Digital Negatives system by Peter Mrhar.  His method for deriving adjustments is effective, comprehensive and includes calibration workflows for scanners, spectrophotometer readings, as well as eyeballing it for those interested in doing it the hard way! Although his color blocking system looked promising for creating deep, rich blacks, foregoing it worked better for our workflow as it was introducing posterization we couldn’t address.

With such highly calibrated plates, I wanted to verify our assumptions about the go-to papers I’ve used for over a decade, and introduce some newer papers, and those we’ve had trouble with before, including 100% cotton papers, which introduced a white haze in our solid, rich blacks consistently.  We’ve generally had much better luck using Hahnemuhle Copperplate papers.  Wood fibers in the alpha cellulose seem to provide more solid fields of black with our workflow and custom 1245 dpi aquatint screen.

The Torinoko 92gsm gampi from Japan had the best fidelity of the three gampi papers we tested this round.  The solid blacks, shadow detail, and crisp transfer from the plate make up for the fragile surface, which can easily be abraded in handling.  The paper has an antique, suede feeling and texture and prints as well as the most expensive gampi papers.

Fine art printmaking papers used in our testing include:

Japan

Germany

UK

France

Italy

* = Waterleaf paper that contains no starch or sizing.

We purchase all of our editioning papers through Takach Paper for their quality service and experience.

NOTE: We have intentionally photographed the images below under a raking light to best illustrate the benefits and shortcomings of the different papers proofed under identical conditions.  All the papers were pre-calendared and had the same approximate drying time.  Click to enlarge details on any of the images below.

Hahnemuhle Copperplate Bright White 100% Alpha Cellulose

Hahnemuhle Copperplate Bright White 100% Alpha Cellulose (detail)

Consistent in continuous tone and image integrity, Hahnemuhle Copperplate remains our go-to paper for proofing and editioning.

Hahnemuhle Durher 100% Cotton Rag

Hahnemuhle Durher 100% Cotton Rag (detail)

Unlike the Copperplate, this radiant white Cotton Rag paper by Hahnemuhle did not hold up as we had hoped. It tested out as the worst paper for photogravure with our plates.  We were consistent in steps for calendaring the paper, as well as printing without to give each paper every opportunity to show its unique qualities.

Arches 88 Proof - 100% Cotton Rag

Arches 88 – 100% Cotton Rag (detail)

This classic waterleaf paper is designed for silkscreen and monotype.  It’s 100% Cotton fiber makeup and zero sizing did not provide adequate structure to absorb the ink from our plates as cleanly as other papers.

Magnani Incisioni

Magnani Incisioni 50% Alpha Cellulose / 50% Cotton Rag – Radiant White (detail)

We likewise had high hopes for Incisioni as it was the brightest white paper we tested.  Although the contrast and quality of blacks created the most photographic-looking prints, it was too much of a good thing.  With work, calendaring and careful assessment of paper moisture before printing we were able to get acceptable results.

Conclusion: While 100% Cotton paper can be problematic in getting optimal continuous tone with Intaglio Editions plates, the cotton papers Lanaquarelle and Somerset Velvet printed relatively well, with the clear champions remaining Hahnemuhle Copperplate “Bright” White and Warm White, and the 92gsm Torinoko gampi for the best looking Asian paper for the price for simple, one-drop photogravure prints and editions.

Wiping and Printing a Polymer Photogravure Plate in 60 Seconds

Recent work with photographer Larry D. Hayden kept us hopping for a few days in August head.  Here’s a little video excerpt showing off Larry’s evocative work and how we printed it.

 

 

Printing Continuous Tone Photogravures from Polymer Plate

Printing for continuous tone using polymer plates is not easy. Not only do you need to be an experienced printmaker to get good results, but you also need to be a plate technician – or have the good fortune of having one in-house: Someone who knows how to render nuances and shadow details from an image and make large plates, without sacrificing sharpness, detail and quality.

This video demonstrates printing with polymer photogravure plates from Intaglio Editions for superior photographic prints. View Intaglio Editions photogravure printmaking video tutorial – and others – directly on our main website.

 

We provide a wide range of traditional fine printmaking techniques and fine print editioning services.
