Account for every reel, sheet and ream from paper intake to packed bundle.

A paper converter buys reels by weight and sells goods by the piece, the ream or the carton, and the gap between those units is where margin goes. Trim waste, set-up spoilage and a reel returned half used all change what a notebook really cost to make. None of it shows on the paper bill.

Paper product software follows the reel from receipt through slitting, sheeting, printing, ruling, folding, pasting and binding. It records grammage, width and moisture on arrival, then the waste at every stage, so a notebook’s cost is read from paper actually used. Packed bundles and cartons are matched to a customer order.

Paper arrives as reels or flat sheets, each with a supplier’s weight, width and grammage. The store books them against a mill and a lot. A planner reads the day’s orders for exercise books, envelopes, paper bags or file covers and picks the reel that cuts with the least trim. Width decides. Slitting and sheeting machines turn the reel into the sizes the orders need. Wide offcuts go back to stock.

Next come ruling, printing, folding, gumming and stitching. Each is run by a small team on its own machine. Operators log pieces made and waste at the end of every run, with the reason when a stack is rejected for creased edges or uneven ruling. Counters put the output into reams or bundles and then cartons. A dispatch clerk pairs the carton count with the customer order, prints the delivery note and loads the vehicle. Short loads stop here.
