Project Newsprint Reel calculator.
Aim : To bring all Newsprint reel calculation in a single window
Time line : 2014-2015
Here I provided reel chart that compare diameter with number of copies and reel weight. This chart can be stick in our Reel stand area that help us to manage reel distribution in production. When diameter and caliper change we know that number of copies get changed. In this chart we tried two different paper caliper and number of copies they yield respectively.

Strip / Flat waste calculation ;
Strip waste chart - as said above we can stick this chart in our press reel room area. This chart gives an idea on how much waste we stripped off from the reel and cost of damage. Click download pdf poster.
Here I have provided calculator for computing - Flat / cut waste before stripping off from the reel. Enter data for example - reel width 1.386 m, paper thickness 60 μm, GSM 42, diameter of reel 1016 mm and measured height of damage reel as like 25 mm. Now hit Calc. button to find the result - 38.2 kg. Like this try some input of your own data and get the result.

A4 210 × 297 (mm) = 1000*2^(-1/4-4/2) = 210 then 210 * √2 = 297 so finally 210 x 297 (mm), like that we can find all paper series size with formula provided next. Here I have attached worksheet for the same, list box cell for input series number to find their size respectively;
