PROBLEM TO BE SOLVED: To provide a technology for printing a ground pattern composite image with an appropriate image density. SOLUTION: A printer apparatus includes a storage means to store ground pattern image data containing a latent image part and a background part, a comparison means to compare a ground pattern density setting value upon generation of the ground pattern image data with the ground pattern density setting value upon printout instruction in case that a printout instruction for the ground pattern image data stored in the storage means is given, a replacement means to replace at least one image pattern of the latent image part and the background part contained in the ground pattern image data with another image pattern having a different density when the comparison means determines that those ground pattern density setting values are not identical, and a control means to print out ground pattern image data in which at least one of the image pattern of the latent image part and the background part has been replaced.
