I am making tests to select the best sizing for my paper-ink combination in gum printing.
To evaluate the sizing efficiency I cover the paper with pigmented gum and develop.
Some stain occurs always, with all sizing composition, and I do not know if I reached an acceptable degree of sizing or not, not having a reference.
Can someone be so kind as to scan a step test paper together with a Kodak Gray scale and make it available to the group?
Thanks in advance,
