3.0 RESPONSIBILITY
3.1 Q.C- Chemist

4.0 ACCOUNTABILITY
4.1 Head-Quality Assurance

5.0 DESCRIPTION:– Visually check the appearance of the sample like colour, shape and physical condition of the sample.
6.0 SHADES OF COLOURS USED:– Visually match the colours used in the sample by shade card provided by the party.
7.0 PRINTING QUALITY:– Visually match the printing matter and quality of printing matter used in



the sample against the approved standard.
8.0 LENGTH:- Take the above five samples and check the length with the help of calibrated scale and report in mm.
9.0 WIDTH:– Take the above five samples and check the width with the help of calibrated scale and report in mm.
10.0 GRAMMAGE OF FACING PAPER:-
Using a template or calibrated scale cut sample of uniform dimensions from the sheet including the release paper.

Note and mark the length of

the sample in cm (L). Note and mark the height of the sample in cm (W). Note the total weight of the sample (W1 g) using a calibrated balance.

Peel off the release paper and note the weight of release paper (W2g) by using a calibrated balance. Using cotton pad soaked in ethyl acetate,

wipe the adhesive side of the facing paper thoroughly by placing the top of the facing paper and wipe off the adhesive surface with a tissue paper.

Wipe the edges on the top side of the facing lightly with some cotton soaked in ethyl acetate to remove any traces of adhesive overflowed to the topside.

Allow it to dry in air till no odor of ethyl acetate is observed and note down the weight of facing paper and weight of sample as (W2g).
Calculate the Grammage of Facing paper by using the formula

13.0 GRAIN DIRECTION:- Apply some water on the back side of the printed matter of the label. Parallel to the label towards the printing side of labels indicates the proper grain direction. Reporting: report as complies/ does not comply
