Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
The embodiment of the present invention provides a kind of digital printing method and apparatus, super large image can be split into the image meeting ceramic tile size specification at random, and efficient printout.
As shown in Figure 1, be the process flow diagram of embodiment of the present invention digital printing method, comprise the following steps:
Step 11: obtain source images;
In actual applications, can determine whether splitting it according to the size of source images, when the length and width of such as source images are all greater than 1m, it be split.
Described source images can be TIF form.
Step 12: determine the area needing the single target printed;
Step 13: if described area is greater than setting value, then netted fractionation is carried out to described source images; Otherwise, strip fractionation is carried out to described source images;
Step 14: the image after splitting is carried out RIP, generates the pagefile that comprises multipage;
Image after fractionation remains TIF form, when generating pagefile, first the converting of image file of TIF form being become the file of PDF, then carrying out RIP to the image file of each PDF, generating the pagefile that comprises multipage.
Step 15: the data of described pagefile are transferred to print system, with by described image printing on described single target.
The method of the embodiment of the present invention can be applied in the inkjet printing to ceramic tile, and citing below describes in detail.
The method of the embodiment of the present invention mainly comprises two parts: 1, the fractionation of image, and 2, the random printing of image exports.
1. image splits
In the embodiment of the present invention, the method that image splits divides two kinds: one is that strip splits, and one is netted fractionation.
When the tile specification that will print is very little, strip is adopted to split; When the specification of ceramic tile is very large, adopt netted fractionation.Such as, source images size is 2m*5m, and single ceramic tile size: 10cm*10cm will adopt strip to split, and namely split into the image block of 50 pieces of 2m*10cm.If single ceramic tile size: 60cm*60cm, will adopt netted segmentation, namely split into the image block of 28 pieces of 60cm*60cm.
A width figure onesize like this, when tile specification is very large, adopts netted fractionation; When tile specification is very little, adopt strip segmentation, such fractionation brings great convenience to process below.If be all use netted fractionation, when single ceramic tile is too small, the block number of fractionation will be a lot, and such RIP will lose time very much.Otherwise when image is very large, the data of print processing will be very large, can bring the difficulty of internal memory application like this to print processing.
2. the printout of image
The image request be printed on ceramic tile be the random image produced (such as, print the product of a row parian, require that the marbling printed wants each difference), the generation of random image can be placed on front end (when image splits) and produce, and produces when also can be placed on printing.
In the embodiment of the present invention, produce when the generation of random image can be placed on printout.Produce because if be placed on front end, a large amount of random pictures produced is carried out RIP, very large pressure can be brought to RIP, a large amount of time can be wasted, efficiency is declined greatly after fractionation.So the part split at random is put into printout part, avoid the RIP process of losing time like this.Efficiency is made to obtain certain raising.Such as: original image is the image 10000 pages that it is split into 30*30cm by 140*120cm at random, if front end produces at random, and carry out RIP and generate printable EJP file, 16 hours (not comprising the time-write interval) of whole process need.And adopt the inventive method, only need 3 hours (splitting in real time, real time print).Improve 5 times.Certainly, this method is also subject to the read or write speed of disk and the restriction of memory size.So machine performance is better, and processing speed is faster.
Fig. 2 is the schematic flow sheet of the image fractionation part that the present invention proposes, and concrete process description is as follows:
Step 21: obtain a large source images (be generally the image of tiff format, length and width are all more than the image of 1m).
Step 22: judge the size of monomer ceramic tile that will print, if ceramic tile very large (such as, can with 30cm*30cm for defining), then adopts netted fractionation; Otherwise, adopt strip inborn ability.
Step 23: carry out netted fractionation.
Step 24: carry out strip fractionation.
Step 25: the image after splitting is carried out RIP, generates the EJP file of a multipage.
After several step above, just a large figure can be split into several little images, then generate the EJP file of a multipage, as the operation of the printing of follow-up random fractionation.
Fig. 3 is the schematic flow sheet that the present invention proposes the printout part of image, and concrete process description is as follows:
Step 31: produce random coordinates, locates the reference position of the image that will print.
Step 32: coordinate points be mapped in original large image, locates this which page in EJP file.
Step 33: the data of related pages in EJP file are read in internal memory.
Step 34: the data read in internal memory are scrabbled up the view data that will export.
Step 35: by data distributing to rear end print system, print.
As can be seen from the above description, the digital printing method that inventive embodiments provides, can split into super large image the image meeting ceramic tile size specification at random, and efficient printout.
