Method for producing elementary moulded board for generating gaze screen mask

Abstract

The invention provides a method for producing a basic template used for generating screen masks, which adjusts the net line number or minimum point arrangement type (comprising cluster dimension or distribution density) of a tested template, prints the tested template with output devices and judges that whether the grey value of the printing result complies with specific grey value; if the grey value of the printing result does not comply with the specific grey value, the net line number or arrangement of minimum point arrangement type is continuously adjusted till that the grey value of the printing result complies with the specific grey value and the tested template is then taken as the basic template. As the method of the invention aims at the output device and carries out the optimum design of the basic template, the output device has optimum effects when being used for screen mask printing, ensures that the minimum colour points are devotedly output, and removes the effects of powder-dropping phenomena on the output results.

Description

technical field [0001] The present invention provides a method for generating a basic template for generating a screen mask, and more particularly relates to a method for generating a basic template for a specific output device (eg, a laser printer). Background technique [0002] In order to express the natural continuous tone with digital technology, so that the output result of the digital printer can be close to the color gamut displayed by the input device, the commonly used technology is called halftone (halftone), which uses a large number of darker colors in the image. The lighter color is represented by fewer or smaller color points, and the difference in the distribution or size of the color points is used to create more visual color changes. The implementation methods of halftone technology can be roughly divided into screen (screening), error diffusion (error diffusion) and direct binary search method (direct binary search). widely used in the world.

Problems solved by technology

[0004] The design of the mask mainly focuses on making the color point change more evenly and making the halftone image output by the printer faithfully present the tone of the continuous tone image, but in fact the output effect of the image is directly and powerfully related to the performance of the printer. For example, when the resolution of the printer is higher, the size of the color point used is smaller, and the image that can be presented is finer, but when the resolution of the printer is not high or the adsorption force of the toner is not good, the too small Or too few color dots often cannot be output normally, and the quality of the final printed image will be affected by powder drop

It can be seen that the mask design suitable for a specific printer may not be suitable for another printer. However, the masks used by general printers are uniformly set by the manufacturer, and there is no individual optimization for the printer. processing, so the quality of printing cannot be guaranteed
