On the basis of the embodiment, the embodiment also provides a processing method of the oil block and the characters in the jet printing layer, which can solve the problem of ink adhesion when the characters in the closed area are jet printed, and also solve the problem of oil block stacking.
The layer processing method comprises the following steps:
s400, acquiring an original jet printing layer; the original spray printing layer comprises a plurality of oil block spray printing areas for forming oil blocks, gaps are formed between adjacent spray printing areas, and the oil block spray printing areas are filled with a plurality of adjacent pixels; the original jet printing layer also comprises a plurality of characters; the plurality of characters comprises a plurality of preprocessing target characters formed with closed areas; illustratively, the pretreatment target characters with closed regions include "0", "8", "4", "a", "D", etc.;
s500, expanding a closed area of the pretreatment target character; therefore, the character optimization of the complex input image layer is completed, the condition of ink adhesion during the character jet printing is avoided, and especially the jet printing effect of jet printing equipment on complex images is improved.
S600, performing pixel pumping on the oil block jet printing area to generate a new jet printing pattern layer; the new spray printing layer is provided with a plurality of spaced block areas and a plurality of expanded characters, and each block area comprises a plurality of adjacent pixels; the processing and detailed steps of the method for the oil block jet printing area are described above, and will not be described.
Specifically, an original jet printing layer is firstly obtained before jet printing, and then a closed area of a preprocessing target character in the original jet printing layer is expanded, so that character optimization of a complex input layer is completed, the condition of ink adhesion during jet printing of characters is avoided, and especially the jet printing effect of jet printing equipment on complex graphics is improved; and then, extracting adjacent pixels in the oil block jet printing area in the original jet printing layer to form a plurality of spaced block areas, namely dividing the oil block jet printing area corresponding to the oil block with larger size into a plurality of block areas, so that the jet printing equipment can adapt to the oil blocks with different sizes during jet printing, the situation that the jet printing is repeated due to mismatching of the ink output of a spray head and the size of the oil block when the oil block with certain size is jet printed is avoided, the problem of ink stacking is fundamentally solved, the thickness of the oil block is uniform, and the printing effect of the jet printing equipment is improved.
Additionally, to improve the execution efficiency of the program, the step S400 may be followed by the steps of:
s410, recognizing characters and oil blocks; the character and the oil block are identified by judging the continuity of the pixels, for example, the distribution and the shape of the pixels at the outer edge are detected, the area formed by surrounding the outer edge is obtained, the actual pixel number in the edge is counted to obtain the actual pixel area, for example, the number of pixels with the pixel values of 1 is counted, and the oil block can be considered when the area of the area is equal to the area of the pixel, otherwise, the character is considered.
Further, the step S400 further includes the following steps:
s401, judging whether the size of a character frame where the character is located is smaller than a preset size threshold value; for example, the size threshold may be preset to 0.5mm by 0.5mm;
s402, if yes, determining that the character is a small-size character;
s403, if not, determining that the character is a large-size character;
s404, inverting the pixel value of the small-size character to obtain an inverted character of the small-size character; it should be noted that step 404 is performed after the size of all the characters is determined; after the small-size characters with the closed areas are reversed, spots are formed in the reversed characters of the small-size characters;
s405, judging whether spots are formed in the reversed phase character or not through a spot analysis algorithm; it should be noted that, the input of the blob analysis algorithm is a pixel set of small-size characters, and since the pixel values of the small-size characters are inverted, the pixel values of the closed areas of the small-size characters are all 0, that is, the blob analysis algorithm can analyze whether there is a blob with the pixel value of 0 in each small-size character (and the blob is surrounded by the pixel set with the pixel value of 1);

s408, expanding the closed area of the pretreatment target character.
Specifically, an original jet printing image layer is firstly obtained before jet printing, the size of characters is judged through character frames where the characters are located, closed areas in small-size characters are analyzed through spots, then pretreatment target characters are separated from the original jet printing image layer, the closed areas of the pretreatment target characters are expanded independently to obtain an optimized target character image layer, and finally the optimized target character image layer is combined with the separated original jet printing image layer, so that the step S600 is facilitated, optimization of the small characters in the complex graph is completed, the situation of ink adhesion during jet printing of the small characters is avoided, and especially the jet printing effect of jet printing equipment on the complex graph is improved; in addition, the small-size characters are firstly identified from the characters of the original jet printing layer, then the pretreatment target characters with the closed areas are separated from the pretreatment layer from the small-size characters, the pretreatment target characters can be rapidly and efficiently separated from the pretreatment layer, especially the small-size characters are found out by judging the sizes of the characters, and then whether the closed areas are contained in the characters or not is judged to find out the pretreatment target characters, so that the processing capacity of a program on pixels can be reduced, the running efficiency of the program is improved, and the processing efficiency of a character processing method is improved.
Further, step S408: expanding a closed region of the pretreatment target character, specifically comprising:
s4081, inverting the pixel value of the pixel of the inverted character, which is contacted with the spot, to obtain the inverted character with the expanded closed area; namely, the spot area in the reversed phase character mentioned in the step S405 is directly enlarged, the area needing to be optimized is not needed to be judged again, the character processing method is optimized, the character processing efficiency is improved, and the jet printing efficiency of the jet printing equipment is finally improved.
S4082, inverting the pixel value of the reversed character after the expansion of the closed area;
the whole character optimization process is fast in processing and high in program execution efficiency.
