Marketplace images need to be the best quality possible as these will be used for creating your finished product.
Images accepted
All images should be uploaded based on the following recommendations:
-
JPG or PNG images (PNGs can include transparency for printing on apparel)
-
Max 100MB
-
RGB Color with sRGB IEC61966-2.1 color profile embedded
-
300ppi
At least 6500px (please see Print Product Dimensions below)
-
The largest current product available has the longest axis of 14400px (for a 32" x 48" print). There is no advantage in upscaling or using an image with dimensions larger than this.
-
If the image file uploaded is too small, it cannot be used for larger products. As a result, your order will be put on hold. We will reach out to you and request an image with the appropriate size to fit the product. This may cause a delay, or the cancellation of the customers order.
Convert to Profile
We view every image before an order is sent for production. If we find an image does not have an sRGB IEC61966-2.1 color profile embedded, we will use the option within Adobe® Photoshop® to 'Convert to Profile' and using the default Conversion Options we will set the Destination Space Profile to be sRGB IEC61966-2.1

Due to the Image Ratio for each print, not every Product we can print will perfectly match your original image so this may require you cropping to the largest size option available so that it can be used on the greatest range of products.
Example: an original 30 x 40" image has a ratio of 3:4 so could be used to print at sizes of 16 x 20", 12 x 16" or 5 x 7" but would not work for a 20 x 30" print which has a ratio of 2:3

You would create a Listing and only have Products selected that are square.
Try and upload your image at the largest size you can so that it can be used with the most number of products.
The largest image will be scaled down in size (Bicubic Sharper reduction) to print smaller sizes.
Image Dimensions too large
If your image dimensions are too large, you may experience an issue when uploading your image to create a Listing. If the image thumbnail shows as missing, you will need to reduce the width and height dimensions closer to our guide above.

Apparel Products
Apparel dimensions are set at 4500 x 5700 pixels (portrait or landscape)
Cropping of Images
If the uploaded file is not the correct aspect ratio for the product, we will crop it to fit. In these cases, the sides and/or top and bottom of the image will be cropped (see graphic below).
If the cropping is extensive, we email the buyer of the print with a screenshot showing how we feel the image would be best cropped to be able to produce for them, if they do not agree, or want the image cropped for their print, then we will refund and cancel the order.
Increasing image dimensions
If you are using recent releases of Adobe Lightroom Classic or Adobe Photoshop, they have introduced an 'Enhance' Super-Resolution tool that uses AI to interpolate the image increasing the pixels 2x size.
