Description
Technical field
The present invention relates to printing technologies, control method, a kind of spray in particular to a kind of ink-jet printing system
The control device of ink print system and a kind of ink-jet printing system.
Background technique
Currently, books and periodicals, image printing generally have biggish dot array data amount, the disk read-write of big data quantity can restrict print
Brush speed is reduced data volume by using compression method, so that reducing disk read-write amount is solution common in the industry.
Ink jet printing has obtained unprecedented development as a kind of not contacting printing material, the mode of printing without printing plate, increasingly
More printing houses introduce ink-jet printing apparatus, and opposite traditional printing, flexibility is high, eliminate the process of printing plate, so that with
After PDF (Portable Document Format, portable document format) file is taken at family, by rasterization process
Dot array data is transmitted to digital control system, control print head carries out spray printing, compares traditional printing, generate from mode of printing
The difference of essence.
However, ink jet printing is also mutually far short of what is expected with respect to the print speed printing speed of traditional printing, needs constantly to improve and improve.Ink-jet
Printing needs to rasterize pdf document, generates the equipment dot array data (i.e. color separation dot array data) of color separation, is stored in magnetic disk media
On, after printing starts, system controller software reads color separation dot array data from magnetic disk media, is issued to digital control system.Herein
In the process, the equipment dot array data amount of color separation is very big, for example: breadth, the 600*600DPI of 474mm × 800mm
(Dots Per Inch, dots per inch), 2bit (bit) locating depth, according to calculation formula:
(Width (width) × XDPI (X-axis dots per inch)/25.4) (Height (height) × YDPI (Y-axis per inch
Points)/25.4) × bitCount (bit number)/8/1024/1024,
It is 50.4MB that dot array data amount of the same colour, which can be acquired, and four colors are 201.6MB, current general disk read-write speed
About 50-100MB/S, under the current space of a whole page, according to the following formula:
Disk reading rate/tetra- colors dot array data amount × 60 second × image panel height,
Being scaled print speed printing speed is about 12-24 meters per minute, and general spray head injection frequency is 30K, according to following public affairs
Formula:
25.4 × injection frequency/DPI/1000 × 60,
Speed is about 74 meters per minute, which can not make full use of the characteristic of spray head, and system controller software cannot
Receive this speed.Therefore, in ink-jet printing system, obtaining generally can be by the equipment dot matrix number of color separation after data with rasterized
According to compression storage is carried out, data storage capacity is greatly reduced, the data volume of disk read-write is reduced, and then improve print speed printing speed.
Based on the above, select a kind of suitable compression method that will seem increasingly important.A kind of applicable compression method
Demanding compression ratio, small calculation amount.A kind of compression method of little compressible, Bu Nengyou limited to the reduction amount of data volume
Effect ground mitigates disk read-write amount, that is, the requirement of system is not achieved；And a kind of compression method of intensive, although reducing disk
The data volume of read-write, but decompression calculations are time-consuming after reading, the supply of data needed for being equally unable to satisfy high speed printing,
The requirement of system is not achieved.
