Only three of them are shown for print station 0. The brewer 38 may include additional rolls, each slightly spaced apart from the surface of the plate roll 32.

Plate roll 32 of lithography tower 30 has a printing plate 74 mounted thereon for transferring silicon material from taper 38 onto a pattern plate that adheres to planket roll 34. . The roll of the dispenser 38 is positioned in relation to the printing plate 74 such that the silicone material is deposited onto the printing plate 74. The dispenser 38 applies silicone material to the entire surface of the printing plate 74. Silicone release layer pattern 24 is shown after it has been transferred onto web 10 from a mold piece of the pattern adhered to the surface of Planketroll 34 . The plates were also printed from the Planketrol 34 by attaching an adhesive backing plate to the Planketrol 34 and maintained at a constant speed of about 80 feet/minute.

Testing of UV cured release coating layer 24 was conducted on commercial pressure sensitive labels of the rubber based adhesive type. Other adhesive labels, such as acrylic and hot melt based types, have been tested with approximately equal removability. label 2
6 is applied either in an in-line process where the labeler is adjacent to the curing station, or in an off-line process where the labeler is remote from the printing press.

For offline process, silicon release layer pattern 24
A roll 60 for pasting and winding up the web 10 is set on the unwinding side of the labeling machine. In the typical normal process of the press, the applicator applies the label onto the silicone release layer pattern 24.

The labeled form is then rolled or folded.

Regarding off-line testing of silicone layer pattern application prior to laboratory label machine application, one procedure is to apply the label 26 to the release layer pattern 24 16 to 20 hours after the printing process. The labeled release coat layer 24 is then placed under a pressure of approximately 1 bond/in² for 24 hours, approximating the pressure that the label 26 would experience when rolled or folded.

The label 26 is then peeled from the patterned release coating layer 24, and the peel strength is measured and ease of peeling determined. Broken transitions, transfer of undercured silicone layers to the label, and other defects are noted.

For the in-line process, as shown in FIGS. 6 and 7, the label 26 is applied immediately after printing the silicon layer pattern and subjected to the U2 curing process.

The finished product includes a patterned silicone release layer 24;
This is a printed part with a label 26 affixed to a predetermined position on the coating release layer. Peel strength and other test measurements can be performed periodically on the finished product. It is noteworthy that the labels 26 applied to the silicone coating 24 immediately after printing and curing of the silicone coating during the test program were comparable to the labels applied 16 to 20 hours after printing the silicone coating. . After peel strength and peel testing, the label 26 is applied to cardboard to test for adhesion.

Above, a method for manufacturing business notepads including a patterned coating layer of a silicone release material cured with UV light has been shown and described.

Applying the silicon layer pattern onto the web is accomplished by a printing press, and curing of the pattern application layer is accomplished by an ultraviolet light lamp located in-line adjacent to the silicon printing station.

The present invention can achieve the above objects and advantages. Although a preferred embodiment has been shown, many modifications will occur to those skilled in the art.

Such design changes can be made without changing the gist of the invention and are within the scope of the invention.
