QTR polymer photogravure calibration

posted on: January 13th, 2019

BWMastery.com has created a Mac-based software tool called QuadToneProfiler-QuickCurve that enables a very streamlined linearization workflow for making digital positives for steel-backed polymer plates. This is a 20-page pdf description of that workflow. PDF files this size choke my CMS, so to download this file, please click this link

A6-ScreenTest.tif

posted on: December 26th, 2018

This file is an image file that is useful in calculating the screen exposure time for polymer plates. Its use is described in the book Polymer Photogravure: A Step-By-Step Manual Highlighting Artists and Their Creative Practice available here. This file saves a step in that it can be used both for determining the screen exposure value for a polymer plate and also can be used for determining the upper and lower limits (Photoshop Levels) that will be used when printing the positive.

A6-Screentest-Template

posted on: December 26th, 2018

This is a downloadable template file that assists in making even screen exposure strips on an A6 plate during the calibration process for polymer photogravure. It is in the form of pdf that should be printed off at 100% scale on a laser printer or inkjet printer. The markings allow an opaque card to reveal additional plate material under the screen in even increments. Its use is described in the book Polymer Photogravure: A Step-By-Step Manual Highlighting Artists and Their Creative Practice available here.

Black and White torture test

posted on: September 15th, 2014

This is a rather large tiff file used to test the smoothness of all your digital negative/positive work. In particular, the positive and negative circle gradients have a way of making ‘ramps’ in your correction curves very obvious.

My dated Pt/Pd manual

posted on: May 14th, 2014

This is a somewhat dated pt/pd printing manual. It was written right before digital negatives really hit their stride. Consequently, some of it seems a little quaint at this point. The formulas and general information have not changed, however.
