Abstract
The present invention provides a control method used in a roller coating production line, wherein by calculating and controlling the theoretical roll surface linear velocity and actual roll surface linear velocity of each roller in a roller coating unit, the rotational speed of each roller is kept consistent with the process speed, increasing production efficiency. At the same time, calculating a pattern misplacement distance in repeat printing by means of code recognition technology, thereby adjusting the rotational speed of each roller, achieves lifelike and holonomic patterning in multicolored printing and extends the printed length of the pattern.
