- printing color images is generally obtained by overlapping at least four basic colors (cyan, magenta, yellow and black). These four basic colors are printed successively in remote printing groups. This distance between groups can generate differences for the path of the strip of paper to be printed, as well as deformations of this band. However, deviations of positioning of the different basic colors affect the quality of the printed image.
- the printing cylinders are coated with a blanket which receives the ink carried by a offset plate, itself carried by a cylinder which has been previously covered with a film of ink and water.
- the blanket cylinder prints on a strip of paper for example which is held by a back pressure cylinder.
- the offset printing process is characterized by the presence of fountain water and the high viscosity inks.
- the fountain water ensures segregation printing areas and non-printing areas and helps balance the offset printing process.
- the presence of water can distort the paper or at least change its mechanical characteristics. This can also cause registry faults between the different printing groups.
- the compressible layer may have a parabolic profile, the variation in thickness of this layer leading to a variation in compressibility.
- the solutions proposed in the state of the take into account only characteristics mechanics of the printing process, such as pressure in the contact area between the two cylinders or the cylinder width.
- the surface properties of the blankets have a significant influence on the quality of the transfer during the impression which depends in particular on the body of the impression, of the quality of the solid areas, of the loosening of the paper, transfer of fountain water to paper, paper debit or record keeping.

- Figures 2 to 7 show different modes of variation of a blanket surface property, according to the cross direction.
- Figure 1 illustrates a printing cylinder 1, on which a blanket is mounted 10 according to the invention.
- This blanket has a layer rectified or polished, or even molded lithographic at least one reinforcement or support layer and at least one compressible layer. The detail of these different layers is not illustrated in Figure 1.
- the lithographic layer of this blanket 10 is such that at least one surface property of the blanket varies on its outer surface, in the cross direction, that is to say in a direction perpendicular to the direction of scrolling of the paper 2 which is illustrated by the arrow F and parallel to the axis of rotation 11 of the cylinder 1.
- Figure 1 also illustrates a plate cylinder offset 3 receiving fountain water and ink, as shown by the arrows G and H.
- Cylinder 1 performs printing on sheet of paper 2 which is held by a back pressure cylinder 4 or a second printing cylinder identical to cylinder 1 bearing a blanket printing the back of the sheet of paper 2.
- the surface properties which influence the quality of printing are especially the energy of total blanket area, the surface energy at polar character and the average roughness of the blanket.
- a printing blanket necessarily has constant properties.
- a blanket is conventionally made continuously then cut and manufacturing techniques do not therefore not allow to generate variations of surface properties in a specific direction.
- Total surface energy and surface energy at the polar character of the blanket can in particular be modified to be variable in the cross direction of the blanket by grafting photochemically onto the surface outer of the blanket, non-stick monomers or oligomers, hydrophilic or hydrophobic.
- This grafting process is carried out on the substrate constituting the outer surface of the blanket.
- This substrate may be made of an elastomeric material to nitrile base which is ground and sanded or obtained by extrusion.
- This substrate can also be produced in a hydrophobic material such as a polyolefin elastomer or a hydrophilic material, such as an elastomer based of carboxylated nitrile.
- non-polar monomers such as as alkane, alkene or fluorinated monomers with, for example example, one or more acrylate functionalities or methacrylate.
- the total surface energy of the blanket is lower or higher than in areas of the substrate not containing such monomers grafted, depending on the chemical nature of said monomers.
- the blanket areas containing monomers based on grafted silicone have more total energy weak than the ungrafted areas.
- these grafted silicone monomers have a non-stick or loosening power.
- the cleavage of the ink film will take place easier.
- Polar surface energy can also be modified according to the transverse direction of the blanket according the invention by grafting onto the substrate monomers which give it a hydrophilic character after grafting.
- the grafting can also be carried out according to the method described in document EP-0 806 304.
- These monomers are for example monomers comprising acid functions, alcohol or amide, such as acrylic acid or acid methacrylic.
- the nature of the monomer or oligomers including for example acid, alcohol or amide functionalities, gives the grafted substrate an acidic, basic or still amphoteric variable in the cross direction of the blanket.
- the photochemical grafting of a monomer on the substrate is produced, after coating with monomer on the substrate, by irradiation of the latter to across a mask with opaque parts and transparent.
- the substrate can be irradiated using radiation high energy ultraviolet, or even using the visible light, an electron beam or even a X-ray.
- the mask used in the process of grafting has a different optical density in the cross direction of the sleeve, or a distribution variable opaque and transparent parts, depending on what cross direction.
- This distribution generates discrete area sizes having surface properties different from those of substrate, variable depending on the location on the surface blanket.
- This distribution can also generate a variable spacing of discrete areas with surface properties different from those of the substrate, depending on the location on the blanket surface.
- the grafting process that is the subject of document EP-0 806 304 can be implemented several times, successively on the same substrate, as this is moreover described in this document.
- blanket surface including its surface energy total and its polar surface energy
- variation in the properties of blanket surface can be obtained by other methods than that described in document EP-0 806 304.
- Mention may in particular be made of a chemical treatment, a ionization treatment or flame treatment.
- Ionization treatment or flame treatment of the substrate blanket both oxidize the surface substrate in the affected areas, and increase the surface energy of the blanket. This has in particular for consequence that the ink spreads more easily on the printing cylinder 1.
- the average roughness of the exterior surface of the blanket 1 can be made variable according to the direction through the blanket by appropriately performing a final sanding or laser machining of the surface outside of the blanket.
- a variation in the average roughness of the surface outer of the blanket in the cross direction can also be obtained directly by molding, when the blanket according to the invention is obtained with a mold having a appropriate surface finish.
- a variation in the average roughness can also be obtained by a hot calendering type process.
- each of Figures 2 to 7 is a diagram illustrating the variation of a surface property of the blanket (PSB on the ordinate), depending on the position of a point according to the transverse direction of the blanket or according to the width (L on the abscissa).
- X corresponds to the width of the blanket.
- the blanket according to the invention is not limited to this type of centered variation.
- the surface property of the blanket may vary from one edge of the blanket to the other, discontinuously and for example by jumps discreet.
- the surface property of the blanket increases from an edge of the blanket to the plane transverse central or median of the blanket then decreases to the other edge of the blanket.
- the variation in blanket surface property can also be keep on going.
- Figure 5 illustrates a variation in the property of blanket surface which follows a profile cubic
- Figure 6 shows a variation of the surface property taking place according to a profile sigmoid.
- Figure 7 defines a variation of a property blanket surface which is continuous from one edge of the blanket to the other, symmetrical with respect to the plane transverse median and which defines a parabolic profile.
