Digital Asset Specification

DPI vs. PPI (Image Resolution)

DPI and PPI define image density for print and digital displays. Mastery of these terms ensures your brand visuals remain crisp across all consumer touchpoints.

DPI (Dots Per Inch) and PPI (Pixels Per Inch) are measurements of image density that determine the clarity and detail of visual assets across different mediums. While often used interchangeably, they serve distinct roles in the production workflow at JU Productions.

PPI refers to the number of pixels displayed per inch of a digital screen. It is the primary metric for our Catalog photography and Scheduled Lookbook® services, where assets are optimized for e-commerce platforms and mobile devices to ensure fast loading times without sacrificing sharpness. DPI, on the other hand, refers to the physical number of ink dots a printer places on a page. This is critical when transition digital assets to physical retail environments, such as in-store lightboxes or large-format window displays for a Mini-campaign.

By utilizing our global intake hubs in Singapore, the United States, and China, JU Productions captures high-resolution source files that provide the necessary pixel density for global brands to scale their imagery from 72 PPI web banners to 300 DPI high-end print catalogs seamlessly.

Why It Matters

For global brands, consistency is everything. Misunderstanding resolution leads to 'pixelated' print ads or 'heavy' websites that slow down conversion. Correct PPI/DPI management ensures that whether a customer sees your product on a smartphone in Singapore or a billboard in New York, the quality of the visual remains premium and professional.

Examples

1. An e-commerce product image for a Shopify store is exported at 72 PPI for fast web performance. 2. A high-fashion creative shot for a Mini-campaign is prepared at 300 DPI for a double-page spread in a print magazine. 3. A digital billboard in Times Square requires specific pixel dimensions that translate to a high PPI for clarity at a distance.

How to Apply

Identify the end-use of your asset before production. For digital-only assets (Catalog photography), focus on PPI and pixel dimensions. For assets intended for physical retail or OOH (Out-of-Home) advertising, communicate the physical dimensions needed to our post-production team so we can ensure the DPI settings match the printer's specifications.

Common Mistakes

The most common error is submitting 72 PPI web images for professional printing, which results in jagged edges and a loss of detail. Another mistake is over-optimizing web images to the point where they look sharp on desktop but blurry on high-density 'Retina' displays, which often require 2x the standard PPI.

Pro Tip

Always capture and archive your original assets at the highest possible resolution (300+ PPI). While you can easily downsample a high-res image for a mobile app, 'up-rezzing' a low-PPI digital file for a physical retail display will result in blurriness and pixelation, compromising brand authority.
