1. A computer-readable storage medium that stores a print control program for causing an information processing apparatus to execute a process for controlling printing by a printing apparatus based on print data including tint block print data created by adding a tint block image having a latent-image and a background image to an image to be printed, wherein said process comprising:
a judgment step of, when printing is performed based on the tint block print data, judging whether elapsed time from a predetermined point of time in using said print control program exceeds a predetermined time period, or judging whether an amount of a tint block print which has printed from beginning of using said print control program exceeds a predetermined amount;
a density adjustment step of, when said judgment step judges that the elapsed time exceeds the predetermined time period or that the amount of the tint block print exceeds the predetermined amount, adjusting a density of at least one of the latent-image and the background image of the tint block image so that the latent-image is visually recognized when the tint block print is performed and, when said judgment step judges that the elapsed time does not exceed the predetermined time period or that the amount of the tint block print does not exceed the predetermined amount, adjusting a density of at least one of the latent-image and the background image of the tint block image so that the latent-image is not visually recognized when the tint block print is performed; and
a control step of controlling the printing apparatus to perform printing based on the tint block print data density of which has been adjusted in said density adjustment step.
