Measure the position of the window carefully. Measure from the left edge of the envelope to the left edge of the window, and from the bottom edge of the envelope to the bottom edge of the window.
Check the ECS window die size chart for your specifications, or contact ECS if your dimensions are not listed.
Windows must be at least 1/4″ from the sides and 1/2″ from the top or bottom of the envelope.
Material options are plain 24# white wove, or with blue security tint. Other materials such as 70# white offset, recycled offset and colored offset require a quote.
