Platina CU:for UV and Conventional Inks
For both UV ink-Conventional ink users, the rollers are subjected to instability caused by chemical changes on the surface of the rollers.Platina CU remains extremely stable for both dimensionally, as well as in hardness.
BENEFITS
- Excellent dynamic properties
- Extended roller life
- Shorter Wash-up times
- Extremely stable hardness & dimension
The inking rollers are normally composed by the ink ductor roller (rubber rollers that first receive the ink), the ink form rollers (rubber rollers that give the ink to the printing plate) and the distributor rollers.
INKING ROLLERS : Suitable for sheetfed application.
We at SIGMA ROLLERS have following grades to meet your requirements.
Platina: for Conventional Inks
Platina CU: for UV and Conventional Inks

Inking Rollers for Better Printing
The inking rollers are normally composed by the ink ductor roller (rubber rollers that first receive the ink), the ink form rollers (rubber rollers that give the ink to the printing plate) and the distributor rollers.
INKING ROLLERS : Suitable for sheetfed application. We at SIGMA ROLLERS have following grades to meet your requirements.
1. Platina : for Conventional Ink
2. PlatinaUV : for UV-HUV and Hybrid Inks
PRINTING INK ROLLERS
Platina : for Conventional Inks
Platina
Ink applications, dimensional stability, Ink transfer and dot gain are the major Issues faced by printers today. Printers who toggle back and forth between UV and Conventional Inks sometimes needs more time before the rollers acclimatize to the new ink and begin transferring properly. Has exceptional quality of resistance to permeability of Ink Into pores thereby maintaining clean knap all the time. UV ink rollers are meant for exclusive printing objects, in which UV Ink can be used for better results.
BENEFITS
- Excellent tensile strength, better dimensional and hardness stability.
- Resistant to oil, acrylates, abrasion and glazing.
- Better ink storage and transferability.
- Superb resistance to swelling & shrinking.
- Hardness stability
- Excellent resilience
PlatinaUV : for UV Inks
Rubber rollers used in UV printing have ink fluidity problems. With Platina UV there is:
Over a period of time, rollers used In UV printing are susceptible to faster rates of ink glazing caused by the ink penetrating into the pores of rubber and filling in these pores.
BENEFITS
- Improved ink transfer
- No roller surface tackiness
- Improved Ink transfer with good film strength
- Faster drying times
- Excellent dimensional & hardness stability
- Less Ink Glazing
- Excellent Dot Reproduction
- Clean velvety surface
- Excellent dot reproduction
Ultima : for Conventional Inks
BENEFITS
- Good resistance to acrylates
- Stabilize temperature in the printing unit
- Lesser heat generation
- Stable production process

Dampening Printing Rollers
The job of dampening form rollers is to take up the fountain solution uniformly from the transfer or metering roller, transfer it to the printing form and provide a good ink-fountain solution emulsion. When a dampening film is taken up by a dampening form roller, the film is stretched, as the dampening form rollers runs much faster than the metering roller.
We offer both Conventional system & Alcolor system of Dampenning rollers.
The job of dampening form rollers is to take up the fountain solution uniformly from the transfer or metering roller, transfer it to the printing form and provide a good ink-fountain solution emulsion. When a dampening film is taken up by a dampening form roller, the film is stretched, as the dampening form rollers runs much faster than the metering roller. Here, it is important that part of the fountain solution is emulsified in the ink. Thin negative lines and structures in the image are kept free of ink by the fountain solution emulsified in the ink which is released, when the emulsion separates under the pressure of the plate roller.
In the dampening unit there are also rollers that receive the water and rollers that give the water to the printing plate. Accordingly, there may be two different dampening systems:
- Conventional system
- Alcolor system
EXPERIENCE INNOVATION THE PROFESSIONAL WAY.
Alcohol Dampening Rollers
Alcohol Damping Roller supplies alcohol for printing objects in the Offset Printing. It is having the mixture of alcohol and water in it, the percentage of alcohol and water varies for machine to machine and depends on the object to be printed. The alcohol roller is used naked or without cover. If the roller has converted from water to alcohol then the diameter should be increased.
Ideal compound for Dampening, Pan and Metering roller for IPA, IPA-reduced and IPA-free printing.
Suitable for Sheetfed&Webfed offset application.
BENEFITS
- Resist wear & tear due to metering action.
- Good and even wetting due to hydrophile (water - friendly) formulation.
- Resists shrinking, swelling, hardening and abrasion.
- Faster startups due to rapid attainment of the ink water balance.
- Light roller settings.
- Good fountain solution transferability.
- Excellent resilience.
We at SIGMA ROLLERS have following grades to meet your requirements
- AquaFLO6 :- For alcohol contents upto 6%
- AquaFLO10 L- For alcohol content 6-10%
