WAN-IFRA is always known for its research approach and as an extension of this service, we extend this research and study approach to suit testing on your materials. So, we offer the following studies to improve its performances before you consume them in the shop floor. So, WAN-IFRA offers a detailed testing and study on newsprint and news ink materials. Also offers a custom research study on materials like newsprint and ink.

IGT Printability Tester used to test newsprint and ink

1.1  Material testing packages

Combination of different tests are grouped as packages to suit the different needs of the customer. For example printability tests package will conducuct the tests to find optimum ink requirement, ink mileage test of an CMYK ink batch on specific paper, print through test and also test to find the trapping (wet-on-wet) property on the primary CMYK inks and ability to produce secondary colors RGB.

Test samples measured after testing at IGT TesterTest samples measured after testing at IGT Tester

a) Newsprint & ink printability tests : Optimum density setup, Ink requirement, Ink Mileage, print through, picking (fluffing), trapping (wet on wet), Set-off, Strike-through.

b) ISO 2846-2 Conformance Test : Ink requirement, Optimum ink film thickness range, Color deviation at different IFT, Transparency.

c) ISO 12647-3 Conformance study for Newsprint & ink : Newsprint shade, Primary & Color shades, Primary & secondary color deviation from ISO, Color space overlap with ISO.

WAN-IFRA is always known for its research approach in newspaper industry. In the past we conducted many researches in our laboratory and presented as reports and even shared our outcome in Indian and global conferences. Even though its served for the whole industry, customization of our study approach was often the request from many. Recently, we taken the study and research to suit your own materials. Here we offer the following studies for your specific materials to know  its performances before you consume them in the shop floor

 a). Best paper in terms of quality standards - By testing results : This study will help in prioritizing the newsprint in terms of quality of the newsprint and printability. 

 b). Newsprint Yield Study - Grammage consistency & Deviation : This special study will check the consistency of GSM and ground facts on the newprint yield. Remember , even small increase from the actual GSM (what  suppose to be) will incur poor yield and ultimately the product cost. 

c). Characteristics study of various GSM of paper -  40 Vs 42 Vs 45 gsm : As many migrate from 45 to 42 or lower GSM, this study will be helpful in finding what all the quality concerns and compromises between your existing 45 or 42 gsm to lower GSM. This will give a comparative study.    

d). Newsprint Storage time study ( 3/6 month characteristic changes) : 

The known fact is that any material has got specific shelf life, whats your storage self life of your newsprint before it looses some of its property. This study will cover the changes in characteristic properties of paper over a period of time.   

e). Ink mileage a study (Different Ink Vs Different paper): 

Ink cost being one of the major cost in print production, its wiser to use the ink which possibly could produce better mileage than other batch or brand. This mileage study will test mileage of different ink on different paper and this will absolute guide to choose the ink with better mileage rather than comparing it with approximate mileage in terms of pages produced per kg (Thi is not calculated on basis of solid printing , instead tints, texts & images, which will vary in every day edition). 

  

 f). Vendor rating  and selection guideline based on paper & ink testing

This study is purely based on testing results of different

materials from differnt manufacturer and suppliers. Vendor rating could be dont based on quality reproduction parameters or based based on financial benefits like better mileage and yield.   

 g). Fountain solution dosage fixing study:

fount consumption.This study will help to fix right dosage % to arrive at right pH and conductivity, will be ideal to conduct when you are switching from one fountain solution brand to another. Random test would also ensure to right % and manage the
