I didn't know anything about kappa tau before. I worked part-time in a photo studio a few months ago. I didn't know until I had this business. Our shop is all ps.

In fact, many times people send a bunch of materials themselves to make a big display board, and then we use ps to make these materials according to the size required by others.

The resolution depends on the size of the picture. Generally, it is 1x 1m with a resolution of about 200, 1X2, 150. If it is bigger, it will be 100.

After completion, save it in jpg format, and then send it to the workshop where KT version is made for others to process.
