Abstract
A lateral edge of a color thermosensitive recording paper in the main scan direction is detected. An edge heating element closest to the lateral edge is specified. The distance W between the edge heating element and the lateral edge of the color thermosensitive recording paper is detected. The proportion of the distance W to the width Wt of the heating element is calculated. Recording density of the edge heating element is lowered according to the proportion. The boundary between the edge of the recording paper and the print image is blurred.
Claims12
A printer having a recording head with plural recording elements being arranged in a main scan direction to record pixels on a recording paper, said recording head recording an image line by line while conveying said recording paper in a sub scan direction, said printer comprising:
- a sensor for detecting a lateral edge position of said recording paper in said main scan direction:
- a detecting section for detecting an edge recording element that is closest to said lateral edge position among said recording elements with the whole pixel in said recording paper;
- and
- a record control section for controlling said edge recording elements so as to decrease the recording density of an edge pixel corresponding to said edge heating element.
A printing method having a recording head with plural recording elements to record pixels on a recording paper, said recording elements being arranged in a main scan direction for recording an image line by line while conveying said recording paper in a sub scan direction, said printing method comprising the steps of:
- detecting a lateral edge position of said recording paper in said main scan direction;
- detecting an edge recording element that is closest to said lateral edge position among said recording elements with the whole pixel in said recording paper;
- and
- controlling said edge recording element so as to reduce the recording density of an edge pixel corresponding to said edge recording element.
