The imaging power threshold is obvious;
The change of state of matter usually needs to occur at a specific temperature;
The specific temperature value of the transformation of the state of matter determines that thermal imaging has an obvious power threshold. Only when the power reaches a certain value can the transformation of the state of matter be realized. This is why the exposure latitude of thermal imaging is generally very large. No overexposure or underexposure is observed within the range of
Image volume high/binary image;
The obvious imaging temperature and power threshold determine that thermal imaging has the characteristics of high value and close to a binary image, that is, material areas with a temperature above a certain value will undergo physical property changes, while areas below this value will There will be no physical changes;
This is the root cause of the thermal image with clear edges and no gradient transition, which determines that thermal imaging can produce excellent hard spots and has the characteristics of high resolution (depending on the laser spot size);
Thermally generated catalyst decomposition system (such as thermally generated acid to decompose polymers);
Pyrolysis inhibition/heat-induced association state change;
Thermally-induced surface dissociation;
thermal crosslinking;
thermal ablation;
Thermosolution (heat-induced material melting, extension, and finally condensation and solidification);
thermal mass transfer;
It can build conventional (with water) offset printing, waterless offset printing, post-processing-free offset printing, flexographic printing, and other direct printing material systems.
