Description
Technical field
The present invention relates generally to the manufacturing field of plate, especially a kind of manufacture method of printing plate.
Background technology
(Computer To Plate CTP) is meant through computing machine the digital page is directly outputed to technological process on the printing plate Computer To Plate.This technology has not only been saved through process before the tradition seals such as laser photo-typesetting output film and artificial assembly, printing down, saved required equipment and the material of intermediate link, the loss, distortion of site, flexible disadvantage have been avoided, reduced the loss of color and level, and in printing process, shortened mass colour adjustment and alignment adjustment time and ink-water balance time, can improve the quality of products greatly and work efficiency.
The pre-coating photosensitive lithography is meant and is coated with the very thin thermal sensitivity of one deck or the technology of photosensitivity coating on a pretreated aluminium plate.In the use, image forms in this coating, the coating of non-graphic part is divided and is taken off by solvent (or more generally be group water solution), expose original treated aluminium plate surface and can not form picture and text, and the coating of picture and text part can not be decomposed, thereby form the picture and text part, this solution is exactly the developer solution of saying usually.In printing process, the aluminium plate surface hydrophilicity of non-graphic part is good, and the coating oleophylic China ink of picture and text part is good, and therefore, the printing ink on the picture and text of the oleophylic part just can be transferred on the paper.
Generally speaking, the coating on the pretreated aluminium plate is to the ultraviolet light sensitivity, and the picture and text part then can be by forming after common positive or the negative exposure once more.
Typical photosensitivity positive-type photosensitive glue is made up of the potpourri that comprises naphthoquinones thing and phenolics.For a long time, people think that in basic solvent, the naphthoquinones thing can effectively suppress the dissolving of phenolics.Current research shows, the inhibition of dissolving is reached (Reiser et Al.Angew Chem Int Edn.Engl 33 2428 (1996)) by combining with protium.
U.S. Patent number is that 6,063,544 patent has been introduced a kind of positive-type photosensitive glue to the infrared wavelength sensitivity, and it is actually and changes the naphthoquinones thing in the common positive photoresists into a kind of potpourri that can absorb infrared radiation.In fact, this simple technology is not as effective with the photoresists that contain the naphthoquinones thing, and according to the U.S. 6,063, the version storage life of No. 544 patent productions is shorter, and is difficult for developing, and is difficult to the non-graphic partial flushing is clean, if want the non-graphic partial flushing totally, alkaline-based developer destroys the picture and text part again easily.In addition, these photoresists laser energy exposure of having relatively high expectations.
Present topmost problem is, to so far, and the plate quality instability that the manufacturer produces, As time goes on, light sensitivity can change.Therefore, its result is exactly that this version has to preserve at low temperatures always, requires to use air-conditioning control temperature always, even also require refrigeration in transportation; But the environment environment is but more than 25 ℃.Like this, its shortcoming is exactly the expense costliness, accumulating inconvenience.
If not accumulating under low temperature environment, will cause needs higher more laser energy in the plate-making process, so-called " dirty in the printing " phenomenon finally occurs, i.e. non-graphic part oleophylic China ink in printing process.
Subsequently, in order to address this problem, people have invented some other method again.
U.S. Patent number is the photoresists manufacturing technology that 6,074,802 patent has been introduced a kind of infrared sensitization, these photoresists except containing phenolics and infrared emulsion, also contain a kind of potpourri meet heat can be crosslinked with phenolics, as a kind of amino cpds.Its purpose is the picture quality that will strengthen after the infrared exposure, obtains more stable picture and text part.But it does not still have well to solve the quality stability problem in the longer-term storage process.
European patent number is that the patent of EP1024958 has been introduced a kind of technology that is heating and curing, and is placed on and surpasses under 50 ℃ the condition several angels of storage to scheme layer more stable cutting into the plate of opening.But this method hell to pay, and production cost and rejection rate have been increased.And it does not have well to solve the low temperature storage problem of product yet.
European patent number be EP1157854 patent description on infrared light sensitive plate occurs the partly cause of dirty problem, the surface that is exactly aluminium plate is produced high surface by alligatoring, to improve the water-retaining property in the printing process.In the light sensitive layer of printing plate, the photographic layer that coarse surface can produce different-thickness in the paddy peak and the lowest point of rough surface is referred to as " Grains " usually.The coating thickness that these are different can require different exposures.Patent EP1157854 explains, for infrared imaging, laser energy can be on the aluminium plate surface very fast being weakened, therefore paddy peak and the roughness influence to the plate of infrared imaging is very big.Therefore, caustic corrosion is used in patent EP1157854 suggestion, so that 10% thickness of the thinnest part of the photoresists of the bossing on aluminium plate surface reaches 0.2um to 2um.But, handle through alkali corrosion, can cause Grains surface " sphering ", can cause the bonding properties of aluminum substrate and photoresists to descend like this, thereby cause press resistance rate to reduce, and patent EP1157854 does not mention the storage problem that can improve and improve plate through such processing.
European patent number is that the patent of EP1300257 has been introduced a kind of new aluminum substrate treatment technology, this patent is used a kind of aluminium plate of special aluminium alloy composition, carry out the electrolysis in two stages, form specific Grains profile, and then oxidation processes (two-stage oxidizing, can select), thus the anti-dirty ability of raising aluminum substrate.Use the tester of the surface roughness tester of standard such as Taylor Hobson in this patent, the surface average roughness of test is 0.45um, just the mean value to the lowest point at certain measuring unit Nei Gu peak, surface.But this patent production run is loaded down with trivial details, and uses this worker's technology can not solve the stability problem of product quality.
U.S. Patent number is that the patent of US2005260934 has also been introduced a kind of Grains technology, and its Ra value is less than 0.4um, preferably can be less than 0.3um, and anode oxide film weight is greater than every square metre 3.0 gram.But the same for the technology that patent provided of EP1300257 with the patent No., the Ra value generally is not of value to printing during less than 0.4um, because be difficult to obtain good ink-water balance like this when printing.And this Ra value in the operation of rolling of aluminium plate just can reach 0.3um, judges that with regard to being difficult to the Ra of 0.3um is effect or the role of aluminium plate own that electrolysis produces like this.
Therefore, need a kind of method of new production convex-pattern type thermosensitive printing plate, to overcome the problems referred to above.
