Note
When designing new applications, use our standard window sizes and positions. This will reduce costs and increase our manufacturing productivity.

Window Types

Introduction
There are two types of windows:

• Rectangular
• Elliptical
  

Comparison of Rectangular Windows and Elliptical Windows
The rectangular shape is the standard window shape. The elliptical shape was introduced in order to improve:

• Feeding of two way cut sheet InfoSealPS forms in the Folder/Sealer
• Stacking on non-impact printers
  

Design Considerations of Elliptical Windows
The curved shape is designed to prevent the edge of the window die cut from catching on the top of the return envelope patch when feeding InfoSealPS forms into the Folder/Sealer from the cut sheet feeder.

Note: The forms may be a continuous InfoSealPS form that is burst off-line and then folded and sealed in the Folder/Sealer as a cut sheet form.

Note: Elliptical windows are NOT recommended for use on the DFS 1000 or 3600 folder/sealers.

Example of an Elliptical Window Design

This example shows how the standard elliptical window looks in proportion to the window material patch (i.e. glassine or poly). It also depicts sample dimensions of the imageable area (the top dimensions), and the overall dimensions of the window center to center (the bottom dimensions in parentheses). Specify elliptical window dimensions on all orders.

Determining Elliptical Window Dimensions
The window die cut has an arch with a " rise at center span for each 1" of total span.

For example: 3" x 1" window will have a rise at center span of " at the top and bottom, and " at the left and right. Therefore, the final dimensions of the window will be 3-1/8" x 1-3/8" center to center to allow the address area to be 3" x 1".

Window Sizes

Relationship to Address
The die cut InfoSealPS window must be 1/8" larger than the address area on all four sides.

Standard Sizes
The following are standard sizes for InfoSealPS windows.

Minimum and Maximum Die Cut
Minimum die cut with a patch is 3/4" x ¾".
Maximum die cut with a patch is 3-3/4" x 3-3/4".

Die Accuracy
Die placement accuracy = ± 1/64"

Exceptions or Alternatives
We can produce windows larger and smaller than the sizes listed above. It is extremely important that the entire system be considered in order to make an intelligent decision as to the viability of larger or smaller window sizes. The form must not only be manufacturable, but also, it must feed on the printer and be able to be folded and sealed on the InfoSealPS Folder/Sealer.
Refer all requests to the Technical Marketing Specialist.

Window Mark Requirements
Registration marks are required on all patched on windows. They are 1/16" in length and are printed at a 30% screen.
Rectangular Windows require two (2) marks at the top, two (2) marks at the bottom and one (1) mark on each side.
Elliptical Windows require one (1) mark on each side of the window.

Note
Alternative sizes require an upcharge. Contact Customer Service for details.

Window Positions

Specifications
Windows can be positioned at the following standard positions:

• Distance from the TOP of the form can be any distance, but no closer than 1-1/2" from the edge of the die cut to the top or bottom of the form.
• Distance from the LEFT EDGE of the form can be:
  

Caution
The window size and position are subject to the printer's capability.

VERIFY WINDOW POSITION COMPATIBILITY WITH PRINTER SPECIFICATIONS!

Exceptions or Alternatives
All other positions require an upcharge. Contact Customer Service for details.

Positioning on Continuous Forms
On continuous InfoSealPS forms, neither the upper nor the lower edge of the window die cut can be positioned within a ¼" area centered across the mid-point of the form to avoid the edges from catching as the forms are refolding during manufacturing. Select one of the templates below to show proper window positioning on continuous forms:

Window Materials

Introduction
There are two types of window material:

• Glassine
• Polyester
  

Glassine
This is our standard window material for heat fusing and non-heat fusing printers.

Polyester
A treated, heat resistant, non-tear, clear imageable poly for heat and non-heat fusing printers. Not recommended for use on high speed continuous laser printers.

Standard Sizes
Standard widths pf glassine and poly window patches are:

• 3-3/8"
• 3-1/2"
• 3-3/4"
• 4"
  

Window Adhesive Patterns

Standard Specifications
The window adhesives will be a 1/8" wide line centered on the ¼" of window material that extends around the die cut. This leaves 1/8" of window material outside the adhesive pattern.

Note: See the diagram below.

The above example is a 3" x 1" window. The window material extends 1/4" around the die cut in all directions. The adhesive pattern is a 1/8" wide adhesive line positioned 1/16" from the die cut. This leaves 1/16" of window material outside the adhesive pattern.

Double Windows

Double Windows
Double windows are non-standard. The window sizes are limited by both the printer and the Folder/Sealer. In addition, double windows may cause problems with postal regulations.

Design Considerations
For most designs the sender's (return) address only requires 3 lines and the outgoing (mailing) address, no more than 5.

Patching Webs
There must be a minimum of 1/4" between the die cut windows. This is because when manufacturing forms with double windows, a minimum ¼" clearance between patching webs is required. 3/8" is desired to support faster running and less cleaning of adhesive patterns.
Patching accuracy in the web direction is ± 1/64".

Patch Depths
When applying more than one patching web on the same patching unit, both patches will be the same depth. Width can vary.

Side-by-Side Windows
When two windows are side-by-side, the windows must be covered by a single piece of material or the windows need to be spaced apart. Windows can be no closer than 5/8". Check with manufacturing.

Postal Problems with Double Windows
Double windows cause postal problems on a two-way InfoSealPS because the envelope face contains the two original addresses plus the return address. The Post Office can refuse mail with three addresses on the face.
Usually, a larger flap can be designed to cover up the original sender's address.
Trying to put the return address on the back of the form does not solve the problem either...then you have addresses on both sides of the envelope, both in the OCR read area. The Post Office can refuse this.
