IGT Pick Test oil

IGT Pick Test Oil for Paper and Paperboard Testing

IGT Pick Test Oil is designed to evaluate the pick resistance and surface strength of paper and paperboard during printing. It is used with IGT printability testers to assess the tendency of a paper surface to pick, delaminate or release fibres under the forces generated during printing.

During printing, the tack and viscosity of the printing ink, together with the printing speed, create forces on the paper surface. If these forces exceed the surface strength of the substrate, damage can occur. IGT Pick Test Oil provides a controlled testing medium for evaluating this behaviour under standardized test conditions.

Available Viscosity Grades

IGT Pick Test Oil is supplied in 70 ml tubes and is available in three viscosity grades:

• Low viscosity (LV): Blue, 17.5 Pa·s
• Medium viscosity (MV): Purple, 52 Pa·s
• High viscosity (HV): Red, 110 Pa·s

Selecting the appropriate viscosity depends on the test method and the paper or paperboard being evaluated.

Applications and Standardized Test Methods

IGT Pick Test Oil is suitable for use in standardized and established printability testing methods, including:

• IGT W31 – Pick and delamination testing ISO 3783 – Pick testing using an IGT printability tester
• IGT W38 – Westvaco pick testing
• IGT W65/W75 – Offset pick testing
• TAPPI T 514 and T 575

It is also used in selected toner adhesion and fluff testing methods.

Why Use IGT Pick Test Oil?

• Evaluate paper and paperboard surface strength.
• Investigate picking and delamination during printing.
• Support printability assessment and paper quality control.
• Select a suitable viscosity grade for the applicable test method.
• Obtain consistent testing conditions when used according to the relevant procedure.
