What precautions does the operator need to take when cleaning the sleeves?

See the cleaning procedure in the relative section.

How should the Sleeves be stored?

Undoubtedly the best way is to store flexo printing Sleeves correctly is to store them vertically in a dry place away from sources of heat or light (particularly away from direct light) – Remember that when handling the Sleeves, they should not be knocked or dropped.

What happens if the Sleeves are stored horizontally, and what printing problems could result?

Printers often store the Sleeves horizontally stacked (or rather “hung”) on tubes with a diameter that is always much less than the internal diameter of the sleeve, in order to take up less space, using solutions that are far from ideal. Unfortunately, ov

The Sleeves are heavy, what can I do?

Manual handling of heavy loads at the workplace has come under increased scrutiny recently, and flexo printing is no exception. For machines with long, wide-format sleeves in particular, the weights involved can be quite high (up to 150 Kg for one sleeve)

When do I have to choose a HM Carrier?

Thanks to its particular construction specifications, the High Modulus Carbon Fibre Carrier - Carbobridge - should be preferred in the following operating conditions:
• Print speed > 300 m/min
• Sleeve width > 1400 mm
• Carrier thickness > 50 mm

Why Rossini with Speedwell?

Rossini has a complete database of all printing machine fitted with the Speedwell system, with the construction designs for the sleeves. Any competitor is able to measure the spindle geometry and produce a sleeve accordingly, but the manufacturing technol

Why choose a conductive rubber?

Conductive rubber is used to ensure constant dispersal of any electrostatic charges generated by friction during the printing process that are not completely eliminated by the electrostatic system. In terms of safety, there is a reduced fire risk from spa

When printing solid colour areas using gravure systems, “colour voids” sometimes appear in the centre, or there are problems of register, or the duration of the coating is less than it should be; why does this happen and what can I do about it?

The problems listed could be caused by several factors, but as far as the clamp roller is concerned, you should check the following: - the geometry - the roller should be contoured in such a way that it makes up for the deflection of the roller, which is 

How should rubber-coated rollers be stored?

Rubber-coated rollers should be placed on a rack, avoiding direct contact by the rubber coating with the ground; the coating could be irreparably damaged. Rollers can be stored at room temperature, or in any case within a range of temperatures from 0 °C t

Is it important to have a sleeve step?

The step is important and must also be correctly sized: as a general rule, a distance of less than one millimetre must be maintained on every side with respect to the plate to be printed; this helps prevent problems of ink returning to the printing area.

How should I choose the right compound for the coating?

Every rubber-coated roller plays a very specific role within what is now one of the most complex industrial processes there is, due to the constant search for new materials, attempts to further reduce the thickness of coupled films, the extension of multi
