As of June 1, 2023, the Knight ADRC can no longer accept credit cards for payment. This also means that poster printing printing is limited to Washington University with payment via departmental ISD in WorkDay. A valid Cost Center number is required when submitting our online order form. Speak to your department’s business office or your PI for your appropriate Cost Center that will cover the cost of your poster.

If you are from GSON, BJH or UHSP, consider using FedExHI/TEC, or an online printer that can process credit cards.

File Revision Fee

As of January 1, 2025, revised poster files submitted to the Knight ADRC poster service between the hours of 12pm and 5pm on Tuesdays will incur a $20 revision fee per submitted revision in addition to the standard cost of the printed poster discussed below. A list of alternative locations that print posters is provided on our FAQ page.

Printing Cost

Foldable Fabric Prints: $0.83/per linear inch

Costs are calculated on a per liner inch basis. This the length of the amount of material that printer uses when printing your poster. It does not necessarily mean the longest side of your poster, but it often is. We round to the nearest inch when calculating the billable length. A cost calculator is provided further below on this page.

Cost Formula: Length of paper used rounded to the nearest inch x 0.83 = Total Cost
