Abstract
From among a plurality of elements included in a printing head and arrayed in a predetermined direction, a faulty element that is unable to form dots properly on a printing medium is identified. At least one of correction processing for increasing a value of multi-valued input image data corresponding to the faulty element and correction processing for decreasing a threshold in a quantization process for the faulty element is performed. Complementary dot data is generated for the faulty element by taking the dot data generated for the identified faulty element as dot data corresponding to an element near the identified faulty element in the predetermined direction.
