Print control program, print control method, and information processing apparatus

A print control method 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, said method comprising:

• 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;
• 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
• 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.

An information processing apparatus 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, said apparatus comprising:

• judgment means for, 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;
• density adjustment means for, when said judgment means 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
• control means for 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.

A storage medium storing, readably by an information processing apparatus, a print control program for causing the 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:

• 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;
• 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
• 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.

A print control method for causing an information processing apparatus to execute a process for creating a tint block image having a latent-image and a background image, the tint block image being added to an image to be printed, said method comprising the steps of:

• holding at least one of the latent-image and the background image of the tint block image, in relation to information on a first density by which normal tint block print is performed;
• changing the first density into a second density higher than the first density after a creating process of the tint block image is executed for a predetermined time period, or after the creating process of the tint block image is executed for a predetermined number of times, or after the creating process of the tint block image is executed for a predetermined number of pages;
• and
• inhibiting the process of changing a density into a density excluding the second density after a density is changed into the second density from executed.
