Also known as Spiral coils, plastikoil, ez-coil, color coil or
colorcoil these preformed spirals offer a highly versatile binding
solution. This makes it an attractive method for those looking for something new and exciting, as well as something that can be mailed and stand up under adverse conditions.
Color coil binding (also known as Spiral coil binding) is a bright, trendy binding
element, that has excellent bounce back memory. This makes it an attractive
method for those looking for something new and exciting, as well as something
that can be mailed and stand up under adverse conditions.
Here are some key points to remember about Coil binding :
There are three primary hole patterns used for coil binding.
The GBC / Ibico 4:1 pattern utilizes holes that are 0.2475” center
to center with 44 holes on an 11” binding edge.
The industry standard pattern for color coil utilizes holes that are
0.250” center to center with 43 holes on an 11” binding edge.
The 5:1 pattern for coil binding utilizes holes that are 0.200" center to center with 55 holes on an 11" binding edge.
GBC / Ibico 4:1 vs. Industry 4:1 -- Documents punched
using the GBC / Ibico 4:1 pattern and the Industry 4:1 pattern both use the
same binding elements. There is no need to use special binding elements with
either pattern. So, why use the GBC / Ibico pattern? Simple … with Industry
4:1, many people were understandably upset with the frequency of paper that
had holes punched off the top and bottom of the binding edges. This was caused
by the holes being spaced further apart (.250” center to center). Ibico
developed a new 4:1 pattern, with the holes slightly closer, .2475”
center to center. This pattern has solved the problem, and has become the
lead pattern for most Coil Binding users.
4:1 Pitch vs. 5:1 Pitch – 5:1 Pitch, with 55 holes
to the 11” binding edge created the same challenge as Industry 4:1 –
PLUS, the number of pages in a 5:1 document are substantially less than in
4:1 since color coil spines are only available in sizes up to 25mm in 5:1
pitch while 4:1 pitch coil is available in sizes up to 50mm.
Length – In the office environment, most coil that
is used is 12” in length; which, when cut and crimped, become 11”
for the 11” binding edge. However, some users do use 36" lengths of coil. These longer pieces of coil are more often used with
AFD equipment and by print shops looking to bind documents in irregular sizes.
Crimping – Coil elements must have the top and bottom
ends of the element crimped, to prevent the coil from slipping through the
holes of the document. This procedure can be accomplished either manually,
with coil crimping pliers or with a semi automatic crimper.
Millimeters vs. Inches – All color coil is sized
by millimeters – ranging from 6mm through 50mm in 4:1 pitch. To determine
the size of a coil, measure the inside diameter.
