QuadToneProfiler-Quickcurve polymer calibration

posted on: January 13th, 2019

Check the downloads section for a new downloadable pdf file that covers the process of creating a linearized calibration workflow for positives used in making polymer photogravure plates. This new piece of software from BWMastery.com allows the use of QTR to create perfectly calibrated positives from which to make polymer intaglio plates.

Here is a direct link to that pdf:

Polymer Plate Calibration with QuadToneProfiler

Normally, this would be a download link, but there is something munged up with my download code and pdf files. I don’t have time to figure it out right now, but it is easy enough to click the link on the pdf and then save it from your browser window a printed or saved version is wanted.

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.

QuadTone RIP Digineg Tutorial

posted on: June 11th, 2014

This is a tutorial I wrote several years ago outlining the steps needed to use QuadTone RIP to create digital negatives for alternative process printing. For those who want to achieve the highest level of control over the digital negative process, the QuadTone RIP process still has no equal, albeit at the expense of a steepish learning curve. This tutorial is my attempt at creating a systematic way to use the QuadTone RIP driver for making negatives (and positives).
