Satin smooth finish Minimizes Emulsification Fights Stripping Smoothens out the ink film No oxidation problems

Our USP is our Installation Ready Rollers (IR Rollers) which come fitted with bearing & circlips, individually packed as per OEM specifications. During the process of recovering old rollers go to lathe machine and bearing puller is also applied for removing old bearings. Both these activities damage the uniformity of center hole which is the reference point for dimensions and machining of the complete roller. This results in eccentricity making rollers’ settings difficult. It takes about 150 microns to get correct nip width and if the roller is eccentric by only 70 microns then the squeeze on other end would be more than 220 microns leading to many printing problems. Get new core and new cover every time ! Made out of New core and rubber cover strictly as per OEM specifications. Zero tolerance Eccentricity. Dynamically balanced at high RPMs. Supplied with premounted components like bearings, circlips etc. FEATURES No premature wear outs and pittings at the end, Enhanced life of bearings and other expensive components, Low heat build ups, BENEFITS OF IR ROLLERS   Quick water & ink balance, Less downtime, Cost savings, Enhanced roller life, Low maintenance, Enhanced component life, No recurring costs, No afternoon dry ups, Maintained ink & water balance.

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  DAMPENING ROLLERS -  AquaFloEx, AquaFlo Alcohol & Water Compatible   Alcohol Dampening Rollers  Alcohol Damping Roller supplies alcohol for printing objects in the Offset Printing Machine. 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.    BENEFITS Resist wear & tear due to metering action. Good and even wetting due to hydrophile (water - friendly) formulation. Resists shrinking, swelling, hardening and abrasion. Reduces start-up waste and achieves fine film thickness of fountain solution on plate. Faster start ups due rapid attainment of the ink water balance. Light roller settings. Good fountain solution transferability. Excellent resilience.

Alcohol Damping Roller supplies alcohol for printing objects in the Offset Printing Machine. 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.

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.

Our USP is our Installation Ready Rollers (IR Rollers) which come fitted with bearing & circlips, individually packed as per OEM specifications.

The invention relates to an inking roller for an inking unit of an offset printing press wherein the inking roller includes a number of zones arranged in the direction of the axis of rotation and at least one ink reservoir in the interior of the inking roller. In each of the number of zones, the at least one ink reservoir is connected to at least one ink exit in the circumferential surface of the inking roller. In inking units of offset printing presses, ink is frequently supplied from an ink fountain or ink reservoir to a group of inking unit rollers by means of an ink fountain roller and ink metering devices arranged along the axis of rotation of the ink fountain. 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.       UltimaUV   :  for Hybrid Inks & UV Inks  2.       UltimaEx    :  for Non UV Inks  3.       Ultima         :  for Conventional Inks        UltimaUV : for Hybrid Inks & UV Inks For UV 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. UltimaUV 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 hybrid UV Ink can be used for better results.  BENEFITS Improved ink transfer Rubber rollers used in UV printing have ink fluidity problems. With UltimaUV there is: No roller surface tackiness Improved Ink transfer with good film strength Faster drying times Excellent dimensional & hardness stability For both UV ink-Conventional ink users, the rollers are subjected to instability caused by chemical changes on the surface of the rollers. UltimaUV remains extremely stable both dimensionally, as well as in hardness. The benefits are: Less downtime because of quick roller resetting Extended roller life Shorter Wash-up times Resistance to ink permeation 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. Less Ink Glazing Excellent Dot Reproduction Clean velvety surface
