Offset Ink Maintains International Print Standards

Sun Chemical has launched Exact PSO, a sheetfed process ink set designed to help printers achieve offset standardisation which, in turn, should help improve efficiency.

PSO or Process Standard Offset and ISO 12647:2 are fast becoming the international language for four-colour process printing, according to Sun.

International print buyers continue to demand the application of process standardisation from their printers so print jobs can be fulfilled in different parts of the world without major variances.

Exact PSO is Sun Chemical's answer to this demand.

It is claimed to be a highly versatile product with mechanical resistance and fully meets the criteria set in ISO12647:2.

The inks are based on vegetable oil chemistry, using maximum renewable resources, which allow printers to conform to increasingly demanding environmental standards, added Sun.

The inks are said to perform well on all straight printing and long perfecting presses and can be used on the majority of substrates for long run and short run work on all sheetfed offset presses.

When used with Sunfount fountain solutions and Suncoat coatings, Exact PSO is claimed to increase productivity, whilst meeting requirements for the highest mechanical resistance.

David French, general manager of Sun Chemical's UK offset division, said: "Exact PSO is more than just an ink.

It is a key element of a calibration process to ensure that the printer's press is set up to conform to the ISO 12647:2 international colour standard.

It is also the result of substantial investment in R and D and years of expertise contained within Sun Chemical.

Our customer technical service is part of the complete Exact PSO service." He added: "We continue to listen to our customers' requirements for printing inks and expert help in installing offset process standardisation to help them improve their productivity and profitability." Colin Norgate, Sun Chemical's UK director of value services, commented: "Exact PSO is just one example of Sun Chemical forming partnerships with our customers to add value to their businesses.

In this case, we are not just selling an ink, we work with our customers to accurately set up process standardisation and monitor it regularly to ensure optimisation.".
