Background technology
What adopt in large format air brushing field is the air brushing machine, and in fact it is the another kind definition of ink-jet printer, is commonly referred to as large format and super large breadth ink-jet printer.Generally more than 1m, maximum can reach 3～5m to the fabric width of air brushing machine, is mainly used in the placard of making large format, propaganda material, outdoor advertising etc.
Below briefly introduce the operation principle of relevant air brushing machine.
The image that the air brushing machine is printed is a raster image, therefore, sending into before the air brushing machine prints with the image that forms such as JPEG, BMP or GIF are stored in the computer, need to be treated to raster image by raster image processor (RIP) earlier, raster image is made of picture element, and RIP handles normally and divides for the raster image data that are made of four kinds of color data of C (green grass or young crops) M (magenta) Y (Huang) K (deceiving) color of picture element.The CMYK color mode is a kind of color mode that colored printing is used.
Figure 1 shows that RIP handles the raster image that obtains, if, the raster image data of picture element 101 correspondences account for 1 bit in the raster image data of RIP output, so, what picture elements one amplitude grating image comprises, RIP will export the bit identical with a picture element number raster image data.
RIP transmits delegation's raster image data to the air brushing machine at every turn, the raster image data of delegation's picture element correspondence arbitrarily in the raster image that table 1 sends for RIP, and numeral 1～10 is represented the sequence number of this delegation's picture element.The realistic colour of each picture element finally need obtain by C, M, four kinds of colors of Y, K or more colors are synthetic, such as, add light blue (LC), pale red (LM).Therefore, the raster image data of each picture element comprise the data of C, M, Y, four colors of K at least, the raster image data that such as, sequence number are 1 picture element correspondence comprise: color C, color M, color Y, color K, if this picture element needs air brushing color C, the bit of color C is set to 1 in the raster image data of this picture element correspondence so, otherwise the bit of color C is set to 0.
| Color C | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
