Definitions

  • This invention relates to cylinder covers for printing presses and is particularly concerned with blankets for use in lithographic offset printing.
  • a rotary cylinder is covered with a printing plate which has a positive image area receptive to oil-based inks and repellent to water and a background area receptive to water and repellent to ink.
  • the plate is then contacted with both water and an oilbased ink, thereby inking the image area and moistening the background area.
  • the cylinder on which the plate is mounted is then rotated so that the surface of the plate contacts a second cylinder covered with a rubber-Surfaced ink-receptive printing blanket.
  • The'ink present on the image area of the plate transfers, or offsets, to the surface of the blanket.
  • Paper or other sheet stock to be printed is then passed between the blanket-covered cylinder and a rigid backup cylinder thereby again transferring the ink from the printing blanket to the paper.
  • My invention comprises the combination of a strong, flexible kink-resistant low-stretch foundation sheet material sandwiched between a fairly conventional ink transfer layer and a readily yieldable resilient support layer formed of essentially incompressible resilient material, e.g., oil-resistant rubber.
  • An essential component is a foundation formed of a strong low stretch fabric such as saponified cellulose acetate, available from Celanese Corporation of America under the trade designation Fortisan, or glass cloth. Although a single ply foundation can be employed, I have found it convenient to use a two-ply structure to facilitate processing, as will become apparent from the further description of my invent-ion.
  • printing blanket 10 comprises foundation 11, which in turn is made up of oriented polymeric film 12 and strong woven synthetic cloth backing 13, unified by adhesive layer 14. To the opposite surface of synthetic cloth backing 13 an ink transfer layer 15 is adhered by adhesive 16, and to the surface of polymeric film 12 resilient compressible support layer 17 is adhered by adhesive layer 18. Support layer 17 is externally subdivided by grooves 19, leaving flat-surfaced islands 20 a functionally equivalent form of this structure, in which foundation 11 is inverted for convenience of manufacture, will be further described and explained with the aid of an illustrative but nonlimiting example, all parts being by weight unless otherwise noted.
  • Example A S-mill film of biaxially oriented polyethylene terephthalate was primed by briefly immersing it in a 10% solution of parachlorophenol in trichloroethane, and passing the film between rubber squeeze rolls, after which the coated film was dried to evaporate the solvent.
  • an adhesive coating made by blending 100 parts of Hycar 1001, 20 parts of dioctyl phthalate, parts of a 50% 0 methyl isobutyl ketone solution of an oil-soluble phenol formaldehyde resin (Durez 14296), and 80 parts of Epon 828, after which the solvent was evaporated by heating for 5 minutes at 275 F., leaving a slightly tacky adhesive film approximately 2.5 mils in thickness.
  • Hycar 1001 is a 60:40 butadienezacrylonitrile rubber having a Mooney viscosity in the range of 80-110.
  • Epon 828 is essentially the diglycidyl ether of bisphenol A.
  • Hycar 1042 100.0 Zinc oxide 5.0 SRF carbon black 56.0 FEF carbon black 38.0 Di-butoxy ethyl se'bacate 20.0 N-nitroso diphenyl amine 2.0 Stearic acid 1.5 Sulfur 1.65 Benzothiazyl disulfide 1.35 Tetra methyl thiur'am monosulfide 0.22
  • this rubber composition is such that when cured and tested in accordance with ASTM Test D 676- T the rubber has a Shore A-2 hardness of 77-78 durometer.
  • the rubber composition was preheated on a warmup mill and then calendered onto the saponified cellulose acetate, the calender rolls being maintained at about 200 F. The total caliper of the structure was found to be approximately 32 mils.
  • the two intermediate products i.e., the rubber coated polyester film and the embossed rubber-coated Fortisan fabric, were laminated on heated squeeze roll equipment,
  • the bonding adhesive was then 7 cured by heating the structure, in roll form, for 8 hours at approximately 260 F.
  • the laminate having a thickness on the order of 72 mils, was rendered of uniform caliper and smooth surface configuration by grinding the unem-bossed rubber face on a conventional drum sander provided with Grade 150 coated abrasive material, and thereafter polishing to remove the grinding marks.
  • the finished structure had an overall thickness of 67 mils.
  • the product of this example was tested by placing it under a load of approximately 1 lb. per square inch, i.e., minimum contact pressure of the caliper gauge. Pressure was then increased to lbs. per square inch, and it was noted that the caliper had decreased between 3 and 4 mils. When the pressure was further increased to 1000 lbs. per square inch an additional decrease in caliper of approximately 4-5 mils was noted. When the pressure was again reduced to 1 lb. per square inch, the total compression set was only about /2 mil. It should be noted that 100 lbs. per square inch is fairly comparable to the pressure encountered in normal printing operations, while 1000 lbs. per square inch is typical of the pressure to which a printing blanket is subjected in a smash or misfeed.
  • the best available printing blankets of the type known prior to my invention compress approximately the same amount, but their recovery is inferior, 3 to 4 mil total compression set being fairly typical. This difference can also be observed in a conventional printing operation, where ordinary printing blankets typically fade 2 or 3 mils-arid often even 4 or 5 milsin the first day of operation, requiring the press operator to constantly adjust the pressure to produce acceptable printing results.
  • printing blankets made in accordance with my invention can immediately be set at 3 mils interference require no break in period, and show no detectable tendency to fade, even after running for a period of weeks.
  • the product of the foregoing example has a machine direction elongation of about 1.5% and a cross direction elongation of about 1.8% when subjected to a force of 50 lbs. per inch.
  • This nearly square characteristic, although not absolutely essential, is highly desirable, since blankets may then be cut in whatever manner most economically uses the sheet material.
  • one full equivalent for the polyester film is a continuous filament glass cloth, e.g., one having a 60 x 58 thread count, a nominal thickness of 4 mils, and weighing 3.16 ounces per square yard.
  • the glass cloth is actually superior to the polyester film described, since it totally eliminates-any kinking problem. Kinking sometimes occurs when a printing blanket is carelessly handled, so that it is bent back sharply on itself at 180. Under such circumstances, oriented polyster film may occasionally retain evidence of the bending and slightly distort the printing blanket itself. Although this problem is minor, the use of glass cloth totally obviates the difficulty. In like manner, glass cloth can be substituted for the saponified cellulose acetate employed in the specific structure described hereinabove.
  • a single glass fabric of appropriately increased strength can be used to replace both the polyester film and the saponified cellulose acetate fabric; .such a structure, however, obviously necessitates some changes in the processing of the finished product. 'At any rate, the finished product should have a tensile strength of at least about 175 lbs. per inch of width, since a printing blanket is typically applied under a tension of, say 50 lbs. per inch and certain printing blankets have cars which localize the pressure applied.
  • the resilient compressible support layer is the resilient compressible support layer.
  • rubber itself is notoriously incompressible, the specific structure described provides void spaces into which the rubber can distort laterally when subjected to a heavy pressure.
  • the width of the embossed grooves is preferably on the order of inch, and should certainly not exceed inch, or it is likely that a pattern will be transmitted to the material being printed.
  • the exact thickness of this support layer can problably vary Within the range of 10-50 mils, but is preferably 20-40 mils.
  • the support layer should be made up of rubber having a Shore A-2 hardness of at least about 60 durometer and preferably about 75-85. If the support layer is significantly softer than this, it will be impossible to obtain an additional 3 mils compression when the loading is increased from 100 to 1000 p.s.i., as is likely to occur in a smash or misfeed.
  • the support layer should contain at least about 5X10 cubic inches of voids per square inch of blanket surface, but the total void volume should not exceed about 40%. If the void volume is less than 5 10- cubic inches either the compressibility will be too low (if the rubber is relatively hard) or it will be impossible to obtain the additional 3 mils compression when the pressure is increased from 100 to 1000 p.s.i. (if the rubber is soft). If the void volume exceeds about 40% it will be possible to obtain adequate compression at 100 p.s.i. if a sufficiently hard rubber is used, but increasing the loading to 1000 p.s.i. does not provide the necessary additional compression.
  • the compressibility of the resilent support layer is also important. If the structure does not compress at least 1 mil under a loading of 100 p.s.i., it will not conform well to the printing cylinder or to the work being printed. On the other hand, if the compression under this loading exceeds 5 mils, it is extremely difiicult to set the press accurately. As noted, if the compression between the loading of 100 p.s.i. and 1000 p.s.i. is not at least 3 mils, a smash will either permanently deform or distort the blanket or actually spring the press itself.
  • the stretch of the finished produch be no more than about 2%- under a tension of 50 lbs. per inch of width. If this stretch figure is exceeded, installation of the blanket is likely either to decrease the overall thickness of the blanket or to necessitate frequent readjustment.
  • any other support layer having the same compressibility parameters and void volume content can also be employed.
  • a foamed rubber having a planar back surface and a void volume within the described ranges may be employed, but the resultant product is likely to be appreciably stiffer and hence less convenient to use.
  • the support layer is embossed, as previously described, the grooves should be external rather than internal.
  • a thin, strong printing blanket especially suitable for use in offset lithography, where it can be subjected to localized pressures caused by misfeeds or accidental debris, under which conditions it compresses to avoid damaging the blanket or the press itself but upon the removal of the compressive force regains substantially all of its original thickness
