Reformulate ink avoiding dyes when unknown plasticizers are involved.

Use proper solvents

Use proper solvents . Effective drying system and proper solvent balance.

Reduce rewind tension

Use solvents that do

Reduce web temp. or reduce dryer temp

Avoid over chilling that condenses moisture on web prior to rewind.

Control web or film temperature

Introduce moisture into after dryer chamber or tunnel

Pass web through remoisturing chamber

Reduce heat and increase volume of air through drying chamber

Use proper solvents

Control air movements so that it does not effect ink drying

Use fountain covers

Clean the plate well before full run.

Use proper solvents

Use correct ink Viscosity and also check viscosity freequently

Adjust drying to suit press speed.

Add wax compd

Set proper pressure between ink transfer roll and plate

Use proper solvent and fountain cover

Control pressure setting of ink roller nip

Select proper ink roll for design and material to be printed

Maintain proper ink viscosity and check viscosity often

Clean or dust material when necessary, avoid too tacky ink.

Use static eliminator bar

Use well dispersed pigment

Filter the ink well

Keep fountains and ink reservoirs closed.

Adjust pressure to

Use 10 point higher durometer roller.

Select fine meter- ing roll or improve doctor blade wipe.

Use slower solvent or increase press speed.

Introduce heat to the edges. Use heat guns

Introduce moisture by using moist sponge.

Prepare moulds to proper floor.

Print with minimum required pressure.

Raise viscosity

Use pure transparent process inks.

Change plate cylinder diameter or change speed differential of fountain roll to metering roll

Thorough cleaning of metering roll.

Adequate solvent re- moval, drying and reduced tension in rewind.

Reset plate pressure and ink viscosity

Perform necessary make ready

Make new plates and new plate cupping.

Check wearing out of plate cylinder, shaft, journals and gear.

Use recommended plates for given material.

Use compressible stickyback.

Use proper ink viscosity

Adjust roller nip pressure as required

Consult roller mfr. for right type of roller to be used for the given material.

Consult ink mfr. for proper solvent blend

Adjust doctor blade to remove excess ink from metering roll cleanly.

Select anilox roll with lower cell volume or lower ink carrying capacity

Add fresh ink and bring to proper viscosity.

Adjust roller nip to get more ink on metering roll.

Consult roller mfrs. for right roller for the given for the given material

Use new anilox roll.

Mix ink well before adding to the fountain

Add pigment conc. if available or consult ink manufacturer.

Add fresh ink and bring to proper viscosity. Add varnish to increase tack of the ink.

Make new plate if mottle is evident on surface. Check plate mould for mottle.

Check and replace anilox wide.

Wash plate thoroughly.

Clean impression cylinders free of foreign matter, inks, waxes etc.

Softer plates may help and more opaque inks may help

Softer plates may be tried.

Adjust with slow drying solvent

Filter ink or replace with fresh ink.

Consult ink manufacturer

study plate-up, mounting and make ready procedures

Adjust web unwind and re wind tension control.

Check draw roll parallel constant, side to side pressure, center wear condition

Reduce dryer temperature

Center forward, backward and side register compensators before manually keying in job register.

Free all idle rolls so that they turn freely mechani- cally. Drive at web speed if necessary.

check and record press alignement

Check stock and change stock if necessary

Change anilox. Select a screen count appropriate for tone work

Check for proper screen angle suitable for process printing.

Balance solvents and check for proper solvent to add.

Check dryer efficiency and temperature.

Use hot air blower to drive the excess solvent.

Reduce line speed.

Use faster solvents. Check between the units and final dryers for obstructions and make sure adequate supply of air and correct temperature is maintained.

The first suggestion apply. reduce ink film to minimum acceptable level.

Reduce rewind tension

Avoid excess pressure at rewind rolls. Apply anti setoff powder to the web. Overprint with non blocking varnish if necessary

Same remedy as No. 4.

Add faster solvents to 1st colour. Increase dryer temp. between colours.

Add retarder to overprinting colour. Check dryer.

Increase press speed and reduce viscosity of second down colour.

Avoid excess pressure at rewind rolls. Apply anti setoff powder to the web. Overprint with non blocking varnish if necessary

Same remedy as No. 4.

Consult substrate supplier

Increase ink film thickness. Check impression, anilox roll to plate to stock.

Clean impression cylinder

Use retarder or speed up the press.

Check anilox and replace if required.

Check ink and solvent used with the ink maker and plate supplier.

Rebuild tack & strength by adding fresh ink or extender or both

Add retarder.

Verify ink formulation with ink mfr. For given material. Check for “souring”, add anti pinhole compound. Check stock for treatment.

Adjust pressure to get a good print.
