How do I fold

Technical office and print shop needs to fold large formats such as A0, A1, A2 and A3 according to the standards.

Lot of pepole ask: “Are there standards? What is the best and fastest way to fold wide format drawings?

There are many standards in the world to fold wide format technical drawings, according to the dimension of the format to be folded, its vertical or horizontal orientation and the title block position where are located the drawing informations. Most common folding standards are the european ones DIN: DIN A 190Mx297mm where the final folded package as an accordion with step 190mm with last panel 210mm; this panel makes a margin on the opposite side of the title block where is possible to use the 4 holes for ring binders; DIN B standard 190 x 297mm for bagging letters and finally the DIN C standard 210mmx297mm classic A4 format that is the most common used
If the documents A0, A1, have a vertical orientation can be folded with program 210 inverse din, since the title block position is located in another corner or with Afnor french standard that allows to fold A0 and A2 format vertically oriented without pre fold.
In the United States there are folding standards Ansi and Architectural as a function of the series of formats i 11″,17″, 22″ and 34″ (Ansi) o the series 12″, 18″, 24″ and 36″ (Architectural)

Does knowing what I print and fold help to make the choice?

Surely identify own type of documents helps to define better needs and minimize costs.

  1. The expected monthly print volume expressed as copies and linear meters is very important; If I use more that 3 rolls monthly it is surely right think to an automatic folding system like an off line folder, while if are used more that 5 rolls monthly it is really necessary evaluate trim and manual folding costs, operations that would be completely eliminated with a fully automatic printing and folding system.
  2. the type of drawings is varied depending on the areas of design, This affects the amount of ink on the copy and, consequently, the possibility or not to fold the copy still wet so ruining the copy itself

  1. Drawing  Size  length x width
    • A0 1189 x 841 mm
    • A1 841 x 594 mm
    • A2 594 x 420 mm
    • A3 420x297mm
    • any length, in this case it is necessary to evaluate the maximum length as all the off line folders fold at max. 2.5 meters with the exception of GERA Babyfolder
  1. Drawing Orientation:
    • horizontal (standard for the mechanical drawings with title block low right)
    • vertical (sometimes used by nautic and architectural drawings)
  2. File type :
    • vector: dwg (Autocad) dgn ( Microstation) etc..
    • raster : tiff, jpeg
    • various: pdf, dwf
    • print file: plt
  1. Fold output dimension:
    • into A4 format (fan and cross fold) with drawing trimmed on 4 sides
    • only fan fold if the drawing has to be trimmed on lateral edge before the cross folding, this occurs when there are printers with only one paper roll.
  1. witch folding program? For reply I have to know how will I use the folder document:
    • do l simply stock and need a final dimension A4? We’ll use the program DIN C that fold 210mm x 297mm
    • do I need to insert it in a ring binder? In this case I choose the program DIN A: 190+20mm x 297mm where in the 20mm of margin
    • I have to use it in a classifier program with plastic envelope DIN B: 190 x297mm
    • for other applications no problem the GERA folders are the only to fold from a min. of 95 mm to 420mm maximum of panel
  2. which printer will be joined? If is needed to get all the printing and folding process automatic it is necessari to identify the printer model that you have or are going to buy for chiose the folding machine

Now that I have all these informations, what can I do ?

I can contact GERA and forward them these informations, so GERA will indicate wich product is more useful to really clarify the benefits of a folding machine.

Do I really need an automatic folding machine ?

How to calculate the point of convenience? Easy: fold an A0 document cost average 1 € so if I print and fold 3 paper rolls every month this means that a qualified person as an engineer or a designer could cost from 300€ to 500€ every month
Printing, trim an folding a color A0 drawing in a reproshop the price is from10 to 15 €
so if you use a printing service you will know what is convenient to have a folder at home
Moreover print and fold at home is not just a matter of convenience but also protection of own drawings (see SPY story  Ferrari Mc.Laren, where Ferrari engineering  drawings have been reproduced by reproshop) or limited time within which the project must be printed and folded
