1. An information processing system comprising:
(a) at least one processor and (b) at least one memory coupled to the at least one processor and having instructions stored therein, the at least one processor and the at least one memory cooperating, when the instructions are executed by the at least one processor, to act as a plurality of units comprising:
(1) a first generation unit configured to generate a reduced image in which an original image is reduced;
(2) a display control unit configured to cause a display device of a predetermined apparatus to display the reduced image;
(3) a second generation unit configured to generate, based on an input to the predetermined apparatus of a user, a mask image to be overlapped on the reduced image displayed on the display device; and
(4) an enlargement unit configured to enlarge the mask image by using (a) a first interpolation method in a case where a color to be expressed by a spot color ink is used in the mask image and (b) a second interpolation, different from the first interpolation method, in a case where the color to be expressed by the spot color ink is not used in the mask image.
