Definitions
- the main subject of the present invention is a improved lithographic layer for blanket printing.
- blankets for offset printing generally include a coated support one or more successive layers, themselves coated with an outer or printing layer commonly known as the lithographic layer.
- the layer lithographic was in an incompressible material, such than nitrile rubber, so as to obtain a good offset printing quality.
- the object of the present invention is to solve in particular the above problems and drawbacks by providing the lithographic layer a certain degree of compressibility which, contrary to all expectations, and whereas the incompressible lithographic layers of prior art were deemed to have the maximum printing advantages, gives said layer very important or even exceptional advantages.
- the lithographic or printing layer according to this invention is made slightly compressible by including a multiplicity of voids in the elastomeric material constituting said layer.
- This layer is further characterized in that the voids consist of pre-expanded microspheres or expandable in the elastomeric material.
- the content of microspheres in the elastomeric material is included between about 0.5 and 10% by weight of the layer and preferably between 2 and 4% by weight of said layer.
- the lithographic layer of this invention is still characterized in that the diameter of the microspheres in the elastomeric material of the layer is between about 10 and 30 microns.
- the lithographic layer according to this invention has a thickness of less than 0.7 mm, and preferably less than or equal to 0.3 mm.
- This invention further relates to a printing blanket comprising a lithographic layer corresponding to one and / or the other of the above characteristics.
- This printing blanket can advantageously coat the shape of a sleeve.
- Figure 1 is a schematic sectional view cross-section of a blanket embodiment printing equipped with an outer layer or lithographic sleeve, according to the invention.
- Figure 2 is a schematic sectional view, more large scale, lithographic layer.
- Figure 3 is a schematic sectional view of the contact area of two lithographic layers incompressible according to the prior art.
- Figure 4 is a schematic sectional view of the external face of an incompressible lithographic layer according to the prior art, after finishing by polishing this layer.
- Figure 5 illustrates the displacement D (microns) in blanket surface, i.e. displacement of the lithographic layer, as a function of position P (millimeters) in the contact area between two blankets.
- a printing blanket 1 which, following the example shown, has the form of a cylinder or sleeve made up, from the inside to the outside, of a support 2 made of metal or other material rigid, of a compressible layer 3 into an elastomer cellular or not, and a lithographic layer 4 according to this invention.
- the support 2 can have a diameter of about 200 mm and a thickness between 0.1 and 0.3 mm.
- lithographic layer 4 other layers (not shown) with the layer compressible 3, that is to say, in general, any combination of layers between support 2 and lithographic layer 4.
- layer compressible 3 that is to say, in general, any combination of layers between support 2 and lithographic layer 4.
- support 2 may be omitted or replaced by means equivalent.
- the lithographic layer 4 which is in one elastomeric material is made compressible by the inclusion of a multiplicity of voids in said elastomeric material.
- This elastomeric material can be any type of rubber known in the art such as rubber vulcanizable nitrile or even combinations nitrile rubber / polysulfide. Also, the material elastomer could be a thermoplastic elastomer crosslinked or not.
- the voids consist of microspheres 5 incorporated into the elastomeric material of the layer lithographic 4.
- microspheres 5 can be pre-expanded and incorporated for example in an elastomeric material thermosetting to form the layer lithographic 4.
- microspheres which are expandable in the elastomeric material, i.e. which contain a solvent which, under the effect of heat at about 100-150 °, causes the expansion of microspheres.
- Such expandable microspheres can be for example incorporated into an elastomer thermoplastic which can be crosslinked or not.
- the content of microspheres 5 in the lithographic layer 4 made of elastomeric material constitutes approximately 0.5 to 10% by weight of said layer.
- a microsphere content will be used between 2 and 4% by weight of layer 4.
- the diameter of the microspheres 5 in the layer 4 elastomer material will be between about 10 and 30 microns.
- the thickness E of the layer lithographic 4 with incorporated microspheres 5 sera less than 0.7 mm.
- the thickness E of the layer 4 will be less than or equal to 0.3 mm.
- the Young's modulus of the layer lithographic 4 will preferably be located in the interval 1 to 8 megapascals.
- FIG. 5 illustrates the results of simulations and tests carried out on the lithographic layer 4, compared to a layer classic lithography of the prior art, that is to say an incompressible bed with no voids.
- the lithographic layer 4 slightly compressible according to this invention will absorb advantageously possible irregularities of any underlying layer, so that the printing surface will be improved.
- the lithographic layer 4 due to its compressibility, will avoid the presence of beads in the contact area between two printing cylinders, i.e. the area where the paper is pinched between these cylinders. In other words, it will only occur significantly no deformation at the surface of the lithographic layer 4, contrary to what was the case, as seen in FIG. 3, with lithographic layers 10 of the prior art which, at the level of the contact zone Z, necessarily had beads B at the entrance 11 of the paper along the path X-X ', and at the outlet of paper in contact zone Z. Faults printing due to these beads B during the rolling of the blankets are therefore removed with the layer lithographic 4 of the invention.
- the absence of beads and therefore of deformations of the lithographic layer 4 will avoid any deformation paper and will avoid any offset or cropping of the colors on both sides of the paper. Any distortion of the printed image will therefore be advantageously avoided.
- the lithographic layer according to this invention is more tolerant of variations in thickness without compromise print quality.
- curve J relates to a layer incompressible lithographic according to the prior art
- curve K relates to a compressible lithographic layer according to the invention and containing a void content or 4% microspheres
- curve L concerns a layer lithographic produced according to the principles of the invention with a microsphere content of 10%.
- the contact zone has a total length of about 8 mm, since it stops respectively on the abscissa -4 and +4 mm.
- the beads B ( Figure 3) created on the surface of the layer lithographic according to the prior art result in displacement peaks marked J1 in FIG. 4 in entering and leaving the contact zone, these beads affecting in particular the flow of paper and creating printing faults as previously explained.
- the invention therefore includes all technical equivalents means described as well as their combinations if these are carried out according to his spirit.
