How to fold large document A0 A1 A2 into A4

There are many standards in the world how to fold A0 drawing paper, 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 190M x 297mm 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 297 mm for bagging letters and finally the DIN C

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’m  folding help to make the choice?

There are basically two ways to handle large format drawings: roll them or fold them. Folding has a number of advantages:

• a folded drawing is easier to archive and takes less space
• a set of folded drawings is conveniently organized in a ring binder or file folder, easy to slip in a briefcase to bring along to meetings
• a set of folded drawings in a binder/folder can be paged through without unfolding, because the title block is always visible in the lower right corner
• once you have flipped through the drawings and found the one you wish to view (or present), a folded drawing is easily unfolded to its full size without first needing to remove it from the binder/folder
• a folded drawing, put in an envelope, is cheaper to sent (by post) than a rolled-up drawing in a cardboard tube

How to fold A0 drawing paper

Surely identify our documents helps to define better our needs and minimize the 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 have an automatic folding system like the GeraFold  folding machine, while if are used more that 5 paper rolls monthly it ‘s really necessary to evaluate trim and manual folding costs ans see the Gerafold online folding solution attached to the printer.
2. The drawing types: colour lines or heavy inked images .

3. How to  fold A0 drawing size  length x width
   • A0 1189 x 841 mm
   • A1 841 x 594 mm
   • A2 594 x 420 mm
   • A3 420 x 297mm
   • any length, in this case it is necessary to evaluate the maximum length as Gerafold paper folding machines have different length capability from 2,5 meters to unlimited length.

4. Folding a0 orientation:
   • horizontal (standard for the mechanical drawings with title block lower right)
   • vertical (sometimes used by nautic and architectural drawings)

6. Package output dimension:
   • we need final package A4 format 210x297mm or Letter A size 8.5″x11″ ? All Gerafold folding machine can reduce your large document down to any package size.
   • First set package size metric or imperial, then set package style depending if the goals is to file the document into a plastic bag or ring binder.

7. Folding program (set the package style)? to answer you need  to know how the document distribution is handled:
   • do l simply stock and need a final dimension A4? We’ll use the program DIN C that folds 210mm x 297mm the stardard 95% of the user use this.
   • 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 is required to make 4 or 2 holes for the rings.
   • I have to use it in a classifier  with plastic envelope DIN B: 190 x297mm
   • for other applications no problem the GERA folding machine are able to provide package dimension from a minimum  of 95 mm up to 420mm.
