(Fin) Understanding Images and Print Quality: A Guide to Uploading and Displaying High-Quality Art and Photography

Introduction

Ensuring high-quality print images is crucial for artists selling artwork online. Poor image quality can lead to unsatisfactory reproductions, affecting customer satisfaction and sales. This guide provides detailed information on supported image formats, resizing images to fit aspect ratios, and photographing artwork for print reproduction.

Terminology

To avoid confusion, here are definitions of key terms used in this guide:

DPI/PPI (Dots/Pixels Per Inch)

The measurement of image sharpness. A standard print DPI is 300, meaning 300 pixels per inch of the printed image.

Image File Format

The type of file an image is saved as, such as JPG, PNG, or TIFF. Each format has different characteristics, including compression, color support, and transparency.

Example: flowers.jpg, landscape.png

Image File Size

The storage space an image file occupies, measured in megabytes (MB). Factors affecting file size include resolution, color depth, compression, and format.

Image Resolution

Measured in width x height (e.g., 1920x1080 pixels), resolution determines image detail. Higher resolution images allow for larger prints without pixelation but result in larger file sizes.

Aspect Ratio

The proportional relationship between an image’s width and height (e.g., 3:2, 16:9). Maintaining the correct aspect ratio ensures the image retains its intended shape when resized for printing.

Image File Color Profile (Space)

The color model used to encode color information in an image file. Common color spaces include sRGB, Adobe RGB, and ProPhoto RGB. The choice of color space affects how colors appear on different devices and prints. Always save your images in the sRGB color space before uploading. This ensures compatibility with most printing systems and prevents color shifts or desaturation during the printing process.

How Product Images are Displayed on Your Website

Your Art Storefronts website automatically generates previews of your uploaded images. These previews help customers visualize how the artwork will look when printed. Be sure to:

Upload high-resolution images to ensure accurate representations.
Maintain the correct aspect ratio to avoid cropping or distortion.
Use an appropriate color profile to preserve color accuracy.

Image Adjustments Made by Your Fulfillment Vendors

Vendors may apply minor adjustments to images for optimal printing. These can include:

Color corrections to match print profiles
Resizing to fit print specifications
Compression adjustments for file optimization

To ensure consistent quality, review your vendor's specific requirements and prepare images accordingly.

Practical Image Preparation Guidelines

Calibrate Your Monitor: Use a color-calibrated monitor to ensure the colors you see on-screen match the printed result.
Soft-Proof Your Images: Use ICC profiles provided by your printing service to preview how the colors will appear when printed.
Export in Supported Color Spaces: Always save your files in sRGB or Adobe RGB (1998) before uploading.

Product-Specific Requirements

Mugs

Ensure your artwork matches the specific template for the mug size you are ordering to avoid trimming.

Canvas and Metal Prints

Save your images in sRGB or Adobe RGB and soft-proof them using ICC profiles to account for darker prints.
Avoid unsupported color spaces like Display P3 to prevent darkened prints.

Bay Photo Prints

Export your images in sRGB to ensure accurate colors and avoid color shifts.

IMAGE SECURITY

ASF has implemented maximum security measures to protect our customers' images, and we have taken it far further than any other art/photography website provider and will continue to do so based on any web updates.

This includes:

No right clicking
no drag-to-desktop
we only display low resolution images optimized for web
we have a watermark tool
site-wide SSL with top-tier encryption technology.

Unfortunately, there is no way to prevent someone from taking a screenshot of your website. This will only give them a low resolution image, but technically, anyone can do this. Therefore the best way to give yourself maximum protection is to watermark your images, similar to how it is done on mainstream stock photography websites.
