Abstract
An information processing apparatus includes a changing unit configured to change an arrangement of pixels which are decided from the first ink data and in which the first ink is printed and the number of dots of the first ink in each pixel, based on the arrangement of pixels which are decided from the first ink data and in which the first ink is printed, and an arrangement of pixels which are decided from the second ink data and in which the second ink is printed.
