Is the photosensitive adhesive used on the transfer printing machine steel plate water-based or oil-based?

Pad printing steel plate is a consumable material used in special printing pad printing machines. Pad printing steel plates include chromium steel, K460 steel, bearing steel, spring steel, and other materials. If it needs to be used during transfer printing, it also needs to be processed once, that is, the content that needs to be transferred is etched onto the steel plate through processes such as applying photoresist, exposure, development, corrosion, etc.
Is the photosensitive adhesive used on the transfer printing machine steel plate water-based or oil-based?
The photosensitive adhesive used for transfer printing steel plates is oil-based, but not the kind of oil-based adhesive commonly referred to by people.
The commonly referred to oil-based photosensitive adhesive is actually a water-based solvent resistant photosensitive emulsion, abbreviated as oil-based photosensitive adhesive, diluted with water.
The photosensitive adhesive used for transfer printing steel plates is actually another system, which is solvent based and solvent diluted as a whole.
