Method for detecting drying performance change of ink

Abstract

The invention relates to a method for detecting the drying performance change of ink, which is characterized by comprising the following steps: a plurality of kinds of ink is placed on a smooth substrate, wherein the variables of the single printing condition of the ink are changed, a plurality of rectangular frames are left on the substrate, printing stocks are padded below the substrate, the ink is placed above the rectangular frames, and a plurality of ink is uniformly scraped into the rectangular frames from top to bottom, the substrate is taken away, and a plurality of ink contrast blocks are left on the printing stocks. The invention has the advantages that firstly, the change condition of the drying performance of the ink along with the change of printing conditions can be predicted, and reference for the adjustment of the ink and the printing conditions is provided; secondly, the drying performance of the ink can be sorted so as to choose the ink with appropriate drying performance and avoid the phenomenon that the ink is pulled up from paper; and thirdly, the method consumes less ink, and detected ink can truly reflect the drying performance change of the ink in the process of printing, therefore, printing work efficiency is improved.

Description

technical field [0001] The invention relates to a method for detecting ink drying performance, in particular to a method capable of predicting ink drying performance changes caused by inks affected by various printing conditions. Background technique [0002] The drying performance control of the ink is very important. It not only affects the printing suitability of the ink on the printing machine but also directly affects the quality of the printed product. Therefore, the drying performance detection of the ink is one of the important indicators for the quality control of the ink. The usual detection method is to test the dryness of the original ink before printing, and its index cannot truly reflect the change of ink drying performance during the printing process, so sometimes the ink dryness index detected by conventional methods is within the normal standard value, but In the printing process, the printed matter is dirty, and the pattern is peeled off in the next printin...
