  1. Welcomes You

  2. HEVEA ENGINEERS PVT LTD MANUFATURERS OF PRINTING RUBBER ROLLERS IN TECHNICAL CO-OPERATION WITH GUMMIWERK KRAIBURG, GERMANY

  3. Value for money Rollers • Our rollers will slash your roller cost substantially and improve your profits • Long trouble free run • Quick ink water balance and Lower startup waste

  4. The HEART of the Printing Machine is the RUBBER ROLLER

  5. Why Printing Rollers are critical to QUALITY Printing quality depends on: • the quality of paper • the quality of ink • the quality of rubber rollers

  6. TYPES OF ROLLERS FOR PRINTING • Letter Press • Offset Inking • Offset Damping • Lamination • Flexo • Gravure • Metal Print • Food Grade

  7. Offset Printing Rollers classified into Ink Distributor Rollers Ink Form Rollers Dampening Rollers Conventional Dampening Rollers Alcohol Dampening Rollers OFFSET PRINTING ROLLERS

  8. ALCOLOR ROLLERS Alcohol : • Bad for your liver • Bad for Rubber Rollers Need special and expensive rubber GUMMI

  9. DAMPING ROLLERS Required Properties • Must be inert in aqueous media • Must have high affinity for water • - Low surface tension for rubber compound • Bareback damping forme roller perfectly even • Alcohol damping – high resistance to alcohol

  10. GUMMI The finest bareback damping rollers in the world. – Likes Water What is GUMMI? GUMMI is a special compound developed with imported polymer from Germany specifically for bare back and alcohol damping rollers.

  11. GUMMI – Likes WaterThe finest bareback damping rollers in the world. Advantages of GUMMI • Dimensional stability • Quick and painless ink water balance • Resist alcohol better than conventional nitrile rollers • Less startup waste of paper/newsprint • Stable water supply and lesser dot gain

  12. IMPORTANT PROPERTIES • Hardness- from 25 to 100 • Resilience - To spring back to its original shape after being subjected to pressure • Evenness- To maintain to ink, fountain solutions, and cleaning an even supply of ink • Chemical Resistance- Resistant agents. • Dimensional stability- Roller needs to remain in proper shape and size even after use

  13. RESILIENCE- critical for inking roller Resilience is elasticity or spring effect Higher resilience means lower pressure setting Lower pressure setting means • Less friction and wear out of plate • Less heat generated and longer life for roller

  14. ROLLER CARE 1. Have Spare set to avoid downtime of your expensive machines. 2. Store the rollers in a cool place 3. Keep Rollers in a storage rack or the packing box 4. Handle Carefully- Avoid contact with sharp edges 5. Ensure bearings are in good condition & change as a pair

  15. Cleaning the Roller • Ink should not be allowed to dry on the roller • When machine stops clean roller with a two step wash. • Clean roller should have a dull velvet finish of a new roller.

  16. Our 6 point INSPECTION Procedure 1. Dimensions : Length, Diameter with verniers. 2. Hardness – 5 different points on roller 3. Visual inspection - For pin hole, defects 4. Runout & Eccentricity 5. Surface test – For air bubbles, low spot 6. Eveness – of diameter using micrometer
