Description
Technical field
The present invention relates to a kind of printing machinery, particularly relate to a kind of offset press numeralization ink-supplying device.
Background technology
At present, multicolour pattern or photochrome, the number of colours on its picture has thousands of kinds.If will almost be impossible these thousands of kinds of color look of the same colour ground printings.So what adopt usually in the printing industry is the method for four-color process.Promptly earlier original copy is carried out color and decompose, be divided into green grass or young crops (C), pinkish red (M), yellow (Y), black (K) four look look versions, carry out the synthetic of color when printing then again.So-called " color separation " is exactly according to the subtractive process principle, utilizes the characteristic of three kinds of colour filters of red, green, blue to the selectivity that coloured light the had absorption of different wave length, and original copy is decomposed into Huang, product, blue or green three primary colors.In the color separation process, by the coloured light of the absorbed complementary color light of colour filter just itself, so that on photographic film, form the negative film of black white image, go screening again, constitute the site negative film, copy, shine into forme of all kinds at last.This is the basic principle of photo colour separation.Because the development of printing technology, now we can by scanning device before printing with the color separation of original copy color, take a sample and change into digital information, promptly utilize with the identical method of photomechanical production the original copy color is decomposed into red (R), green (G), blue (B) three looks, and carry out digitlization, by mathematical computations digital information is decomposed into green grass or young crops (C), pinkish red (M), yellow (Y), black (K) four look forme digital informations with computer again.
Because typography has determined printing can only adopt the continuous tone level of dot reproduction original copy,, will find what picture was made up of the numerous site that differs in size if the picture amplification is watched.Though we see that the site size is different, all occupy the locus of equal size, this is because original image after screening, just segments the image into numerous regularly arranged site, promptly continuous images information is become discrete halftone dot image information.The site is big more, and the color of performance is dark more, and level is dark more; The site is more little, and the color of performance is shallow more, and the level of expression is bright more.The fixed space position size that each site is occupied is by screen frequency decision, and for example, adding site order number is 1501pi, then on one inch length or width 150 sites is arranged.The position in space, site is two different notions with the site size, for example the implication of C50% representative is the C50% that the site size accounts for halftone dot space position, C100% is meant that the site size all covers halftone dot space position, alleged " on the spot " in promptly printing, C0% is not owing to there is the site, has only halftone dot space position, so this piece place does not just have printing ink to be printed on.Obviously linked network order number is big more, and shared locus, site is more little, and the level that can describe is just many more, fine and smooth more.In fact, the level of original copy and color come out by the method for this linked network is reproduced.Here simultaneously also related to the important notion of another one, the coverage rate of space, site (printing ink just), not only the color representation ability of printing depends on this, the supply and the consumption process of printing ink also all depend on this in the final print production.This just relates to the reason that the digitized Comite Internationale de Normalisation of printing process all will determine corresponding interface data format international standard for this parameter.Under the prerequisite that reaches ink equilibrium operating state, the printing ink supply and the consumption of printing process are directly proportional with the coverage rate in space, site, and supply process and consumption process are complementary, and then can produce rich color, the pleasing exquisite printed matter of picture and text; Otherwise, if the supply of printing ink and consumption process do not match, produce at most and be stained with the dirty printed matter that dyes, at least the dull definition that influences of color and luster.Use tens one group of standards to stick to China ink layer on the ink foundation roller perpendicular to the steel disc scraping of ink foundation roller in the printing process of reality and control the ink supply amount: ink foundation roller is relative with the printing cylinder rotary speed constant, the gap of adjusting between vertical steel disc (ink knife key) and the ink foundation roller made the China ink amount change, and had just reached the purpose of adjusting the printing ink supply.Traditional adjustment mode is in vertical steel disc (ink knife key) back manual eccentric wheel (spiral advance and retreat) or ink duct screw (straight line advance and retreat) to be set, and manually adjusts the ink supply state that eccentric manual push rod or ink duct screw handle change each ink-covered area.
In the traditional printing production process, ink supply amount adjustment control is a most frequent job in the operation, inking and damping device must guarantee to reach the even water effect of high-quality even China ink in the very short print cycle, in the hope of obtaining better printing effect, simultaneously in order to eliminate ghost image and ghost, what be popular in now that ink feeding system adopts on the commercial printing machine in city is the direct inking mode that manual ink knife key is handled the vertical scraping ink foundation roller control of ink knife ink supply amount, a kind of space of a whole page of red ink paste used for seals will be cut apart control with tens ink channels zones, cooperate the rotary press of high-speed cruising to do support with the very heavy superpower manual labor of senior leader skilled worker, effect is barely satisfactory.The subject matter that current print production exists is in the print production process, and the operating personnel of printing board often can not see original copy, can only rely on the experience adjustments printing machine ink supply amount of leader, so just often causes the printing mass colour inaccurate; On the other hand, printing accent machine cost rises, the printing quality instability because difference, the factors such as hardware differences between the printing machine of peopleware cause.Regulate and control printing machine ink knife key in advance, not only can not obviously improve the potential risk that print production efficient also can cause ink leak, the adjustment of ink knife key is wasted time and energy, usually need to adjust test and repeatedly just can reach requirement, and the speed of rotary press is quite high, both can produce a large amount of waste products in the mass colour adjustment process, and can waste the precious time again.
