Our Process

We digitally print your art on our corrugated board in CMYK, often referred to as 4-color process, ink with a UV cure. The UV cure ensures your art is set to withstand basic elements and won’t rub off. Our printers are calibrated to SWOP standards, but no two digital printers are the same and we cannot match a PMS color. If color matters to you, please explore our proof options.

Proof and Sample Options

If seeing a proof is important to you, we offer three options:

1. Color Test:

If you are trying to match a color, we strongly suggest using our color sampler to identify the color match you are looking for. Still see a color missing? Chat with a customer service rep and we’ll see if we can add the color for you.

2. Proof:

You can always order a quantity of one with BoxUp. This is the best way to see your art. Turn times for proof orders will vary, please chat with us if you have a specific deadline and we’ll mark it on your order.

3. Printed or Blank Samples:

<p>If you are just looking to see the quality of our printing, in general, or you are looking to have an extra blank thrown in with your proof order, you can order a sample product here.

Product Guarantee

We take full responsibility for the quality of the product. If you are ever dissatisfied with the quality, reach out to us immediately. Our terms and conditions outline our policies on refunds and reprints. Our product is 100% custom. Because of this, we expect our customer to take responsibility for the art product itself. If you want to be sure the end product turns out exactly how you wanted it to, we strongly recommend that you purchase a proof before you place a full order.

Shipping

UPS ground shipping is our default. Our boxes are packed in a corrugated cardboard box usually no more than 50 pounds/each. You will receive a shipping notification when your order is being processed for shipping. Please allow 24 hours for the tracking number to populate your shipping information. Expedited shipping is available on the shipping calculator. If you require special shipping instructions such as blind shipping, a house UPS account or an alternate shipping arrangement, you must reach out to customers service to approve and process your request.
