In the present embodiment, the process of calculating and adjusting for the shop fixtures zone in conjunction with the pattern of simplification explanation the present invention:
Three figures of printing on transparent plastic paper, as shown in Fig. 2, it is the 0-100 rectangular block by white to flavous depth-graded that graph block 21 is one, graph block 22 is blue rectangular block, graph block 23 is the long narrow rectangular block of 6 pixels for width, and graph block 23 visually generally can be regarded a line as.
Fig. 1 has shown a kind of method handling process of printing shop fixtures of the present invention:
According to step S11, at first above-mentioned graph block is carried out the color lump processing, described color lumpization is meant figure, image layout object, converts the processing procedure by the single color lump of figure that has the path gradient information to, and the graph block that generates after the color lumpization is called color lump.In the present embodiment, the color lump processing procedure is carried out according to following steps: at first be that fade effect with object is converted to non-fade effect, the i.e. threshold values that is provided with according to system, taper block 21 is converted to non-fade effect, for the gradient prints object, in carrying out the color lump processing procedure, will give up brightness value and be higher than the zone of setting threshold values.This threshold values is subjected to printed medium, printing ink factor affecting, the threshold values of setting in the present embodiment is 90%, the user can adjust on this basis voluntarily, then new region is calculated profile, the effect of colour mixture is converted to the double exposure effect, promptly calculate current Fill Color for golden yellow, use golden yellow this zone of filling to generate new graph block, graph block 21 is through generating as the piece among Fig. 3 31 after the above-mentioned processing.
The same processing will 22 generate among Fig. 3 32 among Fig. 2, will 23 generate among Fig. 3 33 among Fig. 2.
Step S 12, to above-mentioned figure overall calculation profile, promptly to its overall profile of calculating of the graph block among above-mentioned Fig. 3 31,32,33, generate profile as shown in Figure 4.
Step S13 contracts in the overall profile of calculating among the step S12 carried out, in to contract be the color region that is slightly less than the upper strata image for the color region that guarantees shop fixtures, to avoid in press because the color register trouble causes the color of shop fixtures to spill.As shown in Fig. 5,41 overall profile wherein, 42 shop fixtures profiles after contracting in being for calculating among the step S12, in the size that contracts be set by the user, relevant with factors such as printing precision, printing ink, paper, generally be arranged on 1-10 pixel according to experience, 10 pixels contract in present embodiment is set at.The value that contracts in the image is generally less than the value that contracts in the value that contracts in the figure and the fine rule, and the value that contracts in the image in the present embodiment is 2 pixels.Certainly, the user also can set the value that contracts in, promptly fine rule in contract contract in value, the figure value that contracts in value and the image be the value that contracts in, as for the value that contracts in the fine rule, calculate by the axis of fine rule.
The above-mentioned generally shop fixtures technology implementation method that is treated at present, but for having gradual change or fine rule situation, because above-mentioned processing will cause the effect of printed matter gradual change visually and line fuzzy.Following step is at above-mentioned situation, and the shop fixtures zone that calculate the back of internally contracting is adjusted, and makes the shop fixtures zone better set off out the pattern on upper strata.
Step S14, whether the shop fixtures profile 42 after contracting in the judgement exists the fine rule that closes on, and whether promptly generate contour pattern has the figure that does not have intersection point with shop fixtures profile 42.If exist generation contour pattern and shop fixtures profile 42 not to have the figure of intersection point, then differentiating is fine rule, carries out the finishing of shop fixtures profile.
Step S16 according to the vertical normal direction of this fine rule, enlarges the shop fixtures profile and clings to fine line region.As shown in Fig. 6 since in 10 pixels that contract, and figure 33 width are 6 pixels, so itself and shop fixtures profile 42 no intersection points, the part that then enlarges the close fine rule of shop fixtures profile 42 is close to 33, generates new shop fixtures profile 52;
And then judge whether fine rule 33 satisfies the requirement of shop fixtures, present embodiment is set the fine rule width greater than 2 pixels, divide shop fixtures in then can carrying out, graph block 33 is 6 pixel wide, satisfies fine rule shop fixtures condition, divides shop fixtures in then carrying out, promptly calculate 3 pixels wide, with in abutting connection with the shop fixtures profile with long shop fixtures zone, and merge with shop fixtures profile 52, form new shop fixtures profile 62, as shown in Figure 7.
Step S15, step S14 differentiates the processing of no fine rule or process step S16, zone with 62 li of adjusted shop fixtures profiles, with the calculating that superposes through the graph outline after the step S11 color lumpization, generate new shop fixtures graph block with the overlapping region, be about to the zone of 62 li of shop fixtures profiles, with graph block 31,32,33 stack calculating as shown in Figure 3, generate new graph block 71,72,73, as shown in Figure 8.
Step S17 carries out the shop fixtures color to the new graph block 71,72,73 of above-mentioned generation and fills, and according to the color lump attribute of corresponding graph block shown among Fig. 1 21,22,23, i.e. A: the graph block that contains the gradual change path; B: the graph block that does not contain the gradual change path carries out color and fills, wherein gradual change path gradient, gradual change direction attribute are constant, the gradual change color is the shop fixtures color, here set with redness as the shop fixtures look, then graph block 71, is that the gradual change of 0-100 is filled with white to red gradient, and graph block 73 and 72 is all filled with redness, and the attribute that 71,72,73 graph blocks are set is the double exposure attribute.
So just finished printing shop fixtures figure and generated, as shown in Figure 9.
The present invention is a kind of method of printing shop fixtures, according to the method for the present invention, it mainly is the shop fixtures profile correction of in the above-mentioned processing gradual change color lump and fine rule being carried out, and the attribute of gradual change color lump duplicated, make taper block and fine rule have suitable shop fixtures figure layer, make the better effects if that prints out, particularly " line " seems fuller, clear.
This method is particularly suitable for the printing on the printed medium of transparent or existing pattern, transparent or pattern to printed medium, the existing characteristic that had both kept print media material, make again new typographic pattern contrast vivid, can not be overlapping or image blurring with the color that medium pattern generation double exposure causes.For printing object is image, also can carry out handling according to method of the present invention after the color lump processing, and this method also belongs to innovation scope of the present invention.
By the foregoing description as can be seen, since the present invention be particularly suitable for gradation zone in contract and handle and keep its gradual change setting, for the differentiation setting of fine rule and band transparent processing image, make at the printing effect of the printed medium of transparent or existing pattern vivider, clear.
