Description
Technical field
The present invention relates to a kind of data column print pre-treating method and system, particularly relate to a kind of data column print preceding the data column print pre-treating method and the system of converting colors form fast.
Background technology
Computer system has also comprised the ability of the displaying and the image of prining except editor and processing great mass of data.When prining one page literal, figure or image, the host side data formats must be converted to the acceptable data formats of printer.Generally speaking, for the printer that must use dot chart data (bit-map data), computer information can be translated to earlier required dot chart data (bit-map data). and each bit (bit) among the figure is represented an every bit in the page or leaf of prining.Dot chart normally results from host side. and be transferred to the printer end with compressed format.The dot chart data of compression is to untie at the printer end, and is converted into suitable voltage with the image of prining.
With a laser printer is example, and its each inch (inch) has 300,600 or more pixel usually.A data bit of each pixel ordinary representation printer memory body (memory body is storage medium, storer, internal memory below all is called memory body).For with regard to the laser printer of every inch 300 pixels, the dot chart data that stores a whole page or leaf approximately needs the memory body space of 1MB with regard to resolution.Some laser printer has the mass memory body space, and with page mode (page mode) operation, and wherein page mode is meant that computer end once can handle the dot chart data of a whole page or leaf.Because page mode needs a large amount of memory bodys, also some uses fragment schema (banding mode) to reduce the memory body demand.Use fragment schema the page or leaf of prining can be cut into some levels or vertical fragment (bands).Allow dot chart data that printer once only accepts a fragment to reduce the memory body demand, just accept second fragment when handling first fragment.For instance, under fragment schema, the page or leaf of prining is cut into four fragments, so its memory body demand is as long as use 1/4th of page mode.
In addition, in the process of prining, image data or Graphic Documentation often need by a color format conversion to another color format.The host side of general computer system is in order to cooperate the needs of display, what its image data or Graphic Documentation used is R-G-B (RGB) color format, and the printer end uses the ink of various different colours to be mixed into desired color usually, and therefore the color format that adopts is bluish-green-purplish red-Huang-Hei (CMYK).So, when image data transferred to the printer end by host side, its color format must convert the CMYK form to by rgb format and could supply printer identification and then execution to print.Yet for the color format conversion of the page or leaf of prining, general printer still uses page mode at present.Therefore, the conversion of color format and compression required time are can be with the number of every page of data quantity different, so cause homepage (first page) the output time delay of prining easily.
See also shown in Figure 1A and Figure 1B, Figure 1A is the color format conversion system diagram that has known page mode now; Figure 1B is the Data Processing program synoptic diagram of Figure 1A system, and it is divided into four-stage.Color format conversion system 10 has a data and distributes a module 11 and a Data Processing module 12.In the phase one, data distributes module 11 to receive one to print after page data 20, promptly export one first memory body, 13, the first memory bodys 13 to and store some and the relevant proprietary order (META command) of page data 20 processing of prining simultaneously.First memory body 13 just may be output to Data Processing module 12 after must waiting for that page data 20 of prining writes fully.In subordinate phase, carry out the conversion of color format in the Data Processing module 12, for example rgb format is converted to the CMYK form; Change into the unit 40 acceptable form of prining, for example dot charts of prining afterwards again.Recompression at last is stored in second memory body 14.In the phase III, the data that is stored in second memory body 14 is passed data distribution module 11 back again to be dispensed to the unit 40 of prining.The quadravalence section is that page data 20 whole pages or leaves of prining that dispose are output to unit 40 required times of prining.What deserves to be mentioned is that each stage of prior art can't carry out simultaneously.

Rgb format Graphic Documentation with a 96MB is an example, and when it converted thereof into the Graphic Documentation of CMYK form through host side, its archives size increased to 128MB.Because the method for existing known converting colors form is whole page or leaf pattern to be divided into four achromatic sheet layers of CMYK make color format conversion, and the step of " chromatography " therefore must be arranged, with four achromatic sheet plies to constitute whole colors of this Graphic Documentation.After this step, this Graphic Documentation size can become 16MB.At last, this Graphic Documentation again through overcompression to transfer to the unit of prining.Could begin the output homepage of prining after the so huge Data Processing of unit wait earlier before prining of prining is intact, its stand-by period is obvious of a specified duration excessively.
Tracing it to its cause is, the color data of whole page or leaf pattern is divided into four achromatic sheet layers of CMYK and makes color format conversion in the page mode, therefore time of being equivalent to handle four pages of achromatic sheet layer data time of every processing one page data.After four achromatic sheet layers of the CMYK of every page of data all dispose, chromatography and the conversion form of prining in addition.
In summary, the each data quantity of handling of existing known techniques is big and can't parallel processing, has postponed homepage (first page) output time and the reduction efficient of prining of prining.
