thick as is the case for compressible layer 1 shown in fig1 the single reinforcing layer 4 sandwiched between compressible layers 1 a and 1 b shall have a young elasticity modulus of between approximately 500 and 10 000 mpa throughout the x axis parallel to the orientation of blanket b see fig5 reinforcing layer 4 can be made of a textile grid or of a plastic polymer film such as polyester or polycarbonate and can consist of one or more layers it shall be between approximately 0 05 and 0 8 millimeters thick this type of reinforcing layer 4 offers the advantage of reducing the thickness of the blanket which maximizes the ability to roll and distribute it indeed this blanket can be distributed in rolled form to printers who in turn cut it into the appropriate size and shape to fit their offset printing presses which operate with various and disparate formats in the variation of the blanket shown in fig3 we see this version of the blanket is quite similar to that in fig2 it includes the addition of one paper not shown flow control layer 5 sandwiched between the layer of compressible material 1 a and the lithographic layer 2 and a second paper flow control layer 2 sandwiched between the other layer of compressible material 1 b and lithographic layer 3 these paper flow control layers 5 and 6 have a young elasticity modulus of between approximately 200 and 1000 mpa on the x axis parallel to blanket b 39 s orientation these layers can be between approximately 0 05 and 0 4 millimeters thick furthermore these two layers 5 and 6 can be made of an appropriate elastomer reinforced by fibers paper flow control is improved as a result of layers 5 and.
