In this post, I promised to put up an Ink Evaluation Form. It performs the functions of - recording your recipeshowing people what it looks like and how it behavesif appropriate, comparing your blend to the ink you are trying to replicate I have attached versions in A4 and US Letter, as PDF files. The A4 is the original and the US Letter is that form slightly squished to fit US Letter paper. If anyone wants the original Libreoffice Drawing file to make a native US Letter version, pm me and I will send it to you. You will also need Libreoffice (Mac, Windows or Linux) which is a free download. Moderators, is there any chance of pinning this if there is any interest, so it doesn't get lost?
