Storage and handling of the basic raw materials, paper, boards, plastics are the main functions. Paper is a very expensive material. Paper warehouse must therfore be well organized.
Extremes of temperature and humidity
Must be avoided. Stock is to be kept in a clean and tidy condition. An efficient system of stock keeping, proper paper receipts and issues accounted in ledgers, and a card Index system are required.
Sufficient racks, pallets and other forms of mechanical material handing for transportation of stock in sheet and reel forms, equipped with guillotines for trimming, squaring, cutting of paper for printing section are required.
Printed Paper Warehouse
From simple folding to magazine work, laminated or varnished label work, show cards, perforated duplicate triplicate receipt books, production of paperback books are undertaken here.
All books with limp covers are done here. Case work and hard cover are the responsibility of the bookbinding section. There is an overlap between warehouse and binding sections and some work is handled by both.
All leaflets, folders. Brochures, devising and similar literature requiring only cutting and folding on the buckle folder are handled here.
According to the substance of the material creasing and folding can be employed. Equipment for wire stitching and thread stitching and looping are available here for such type of work.
Large rotary presses print magazines and the work enters the warehouse folded and saddle stitched and trimmed to complete the job. Automatic three side trimmer handles such magazine work. Sheets of magazines are folded, inserted, saddle stitched and trimmed.
Large knife folders or combination knife-buckle folding machines are used according to sheet size, imposition and number of folds. Inline inserters stitches and trimmers automatically accomplish these operations in one unit.
Square back volumes require operations different from saddle stitched variety. Folded sections need gathering, side stitching, covering and trimming. A single inline unit can do all these operations, glue the spine for the application of a drawn-on cover and finally trim the three sides. Thread sewing is expensive. Sewn book is then glued and covered on a wrapper unit and finally trimmed.
Research and development in the making of adhesives has allowed the paper-back industry to grow into a highly specialized section of print, finishing. Perfect, unsewn, thread less, thermoplastic binding is employed for paper backs. Folded sections are first gathered into books, sewing and milling at the spine reducing the sections to a block of single leaves, gluing the spine and drawing-on a paper cover, pressing and trimming being the other operations. A single in line unit incorporates all these operations in a single unit for adhesive binding.
Duplicate, triplicate and multi-set work involves punching, paper drilling, numbering, perforating being warehouse operations for receipt bookwork:.
Multi-punch treadles, paper drills, treadle or rotary perforaters, combined numbering and perforating machines, sheet collating equipment are the equipment required for such work.

Saddle wire stitching and flush trimming are also called for. Plain or printed manila covers, quarter binding are usually employed for multi-,set work.

Varnishing or lamination serves a double purpose: it adds luster to the finished print and forms a protective coating. Size, material and quantity to be varnished or laminated decide the type of machine to be used. Gluing, mounting, cutting and creasing platens or cylinders, cording, stringing and eyeleting equipment, and punch cutting and programmatic or manual guillotines for label work are also needed.
