[0066] With Adobe Photoshop as a tool,
[0067] (1) Make the main image for printing: Create a new CMYK four-color digital file with a resolution of 2800dpi and a size of 5cm×5cm. , Y, and K channels are separated and processed with the custom screening function, that is, a single channel is selected to perform "image / mode / bitmap" processing, and the parameters are set to output resolution 2800dpi, and halftone screen is used. The frequency (number of screen lines) is 175lpi, the shape is circular, and the screen angles of C, M, Y, and K channels are 15°, 75°, 90°, and 45° respectively. Convert the information of the four channels into a grayscale mode, and the conversion ratio is 1.
[0068] (2) To make hidden text in the K version, the basic method is to write hidden text in the K channel, activate the font layer selection, and then delete the font layer. Put the navigator in Photoshop to the maximum (320%), and use the move tool to move the text or image selection, namely...
