INSTRUCTIONS FOR APPLYING PERFECT PERF

NOTE:It is recommended that a good perforation guide be included in the printing plate.

STEP 1:Make certain that the impression cylinder is clean and free from oil or grease.

STEP 2:After positioning image on sheet,transfer image to the impression cylinder.

STEP 3:Cut off the amount of Perfect Perf to rule required and remove the paper backing to expose the adhesive coating.

STEP 4:Following the guideline ,apply the Perfect Perf to the impression cylinder .Once applied the adhesive wll hold the rude in position.

STEP 5:Overlay the rule with the clear film tape furnishined in the spool.On the first impression the sutting or scoring adge will puncture through the tape.

Note:After securing the rule to the cylinder ,it is advisable to reduce the pressure between the impression cylinder and gradually increase until the desired printing and perfrating results are acquired . By increasing the cyclinder pressure it will naturally improve the perforation but could affect the print quality.Therefore depending on the thickness of stock being used it may be necessary to adjust the rule height by building up the rule as suggested below.

TROUBLE-SHOOTING HINTS

If the cut is considered too light, apiece of clear film tape should be applied underneath the rule to adjust the height.Be certain to trim away any extra tape .

If the sheet will not release from the rule or if the cut is considered too heavy,another piece of clear film tape should be applied over the rule.

CAUTION:BEFORE TURNING ON THE PRESS MAKE CERTAIN THERE IS CLEARANCE BETEEN PRESS PARTS AND THE APPLIED METAL RULE.
