Until recently, resizing your image for printing without losing quality was something on the verge of magic. In this process, there are a large number of pitfalls and obvious technical difficulties. All the flaws are visible when printing a low-quality image, so choosing a reliable progressive tool is essential to overcome them all.
Our guide will analyze how to enlarge an image to print without losing quality and explore suitable tools for saving width and height proportions during printing. Let’s get started!
What is image resolution, and why is it important?
Speaking about printing images, it is immediately necessary to clarify what image resolution is and why it is so important. The image resolution is measured in dots per inch (DPI), a generally accepted measure. The parameter determines how many dots of ink will be placed on one square inch of the image. The recommended DPI for printing (especially for hand-held items such as business cards, flyers, etc.) is 300 DPI (300 DPI is ideal for printing hand-held items like business cards and flyers) or 600 DPI (for very fine or high-detail work). However, for more oversized items, such as posters, 150 dots per inch may be enough, depending on the viewer’s distance.
An example of the difference in resolution from the camera on preview:
For example, if you want to print a photo without losing quality. Its size is 8×10 inches; you will need an image of at least 2400 x 3000 pixels (300 DPI).
Main problems when working with image enlargement
When you enlarge the photo, a number of problems arise, and they are mainly due to the fact that services for such purposes stretch the pixels without adapting to the new size. Another common problem is simply adding pixels without taking into account their content, which always leads to pixelation and loss of clarity. The more enlargement is required, the more noticeable these defects are due to the greater number of such additional pixels.
Let’s consider a few more problems:
Low original resolution
To print high-quality images on canvas, it’s important to focus on the number of available pixels, not just the DPI (dots per inch), usually listed in the file’s metadata. So, an image with a resolution of 72 DPI is not necessarily of low quality; the overall size of the pixels affects the quality. So, if you’re printing on a 15-inch canvas, you’ll need about 4500 pixels to reach the required 300 DPI for optimal print quality. However, if your image is only 1080 pixels wide (which equates to 72 DPI), the print will appear low-resolution at that size. Conversely, printing 1080 pixels on a 3.6-inch canvas will still produce a high-quality print at 300 DPI.
Artifacts appear when enlarging
An image artifact is an unwanted effect (such as abrupt color transitions, noise, or jaggies on the edges of objects) that can occur significantly when working with or enlarging images. As a photograph is enlarged beyond its native resolution, more artifacts appear and affect the appearance of the new image. While this issue is not specific to printing, the higher DPI (dots per inch) required for printing—typically 300 DPI compared to 72 DPI for web images—increases these artifacts.
How AI helps in working with images
It is difficult to imagine an area where AI has not proven itself or improved processes. The use of AI in photo enlargement has literally transformed the field and advanced it to a new level. Let’s consider the application of this technology using the PicsArt API image processing platform as an example.
- Image analysis: Working with images begins with the AI comprehensively scanning pictures to analyze them, including studying the contours of objects, textures, and colors. That is, the AI does not guess which pixel should be inserted; it knows this since it clearly understands what is depicted in the photo.
- Pixel prediction: After analysis, neural networks recreate and generate new pixels, adapting the image to the new required size, either it is cropping or enlarging image for print. Let’s look at photo enlargement using a necklace as an example. When the original image is enlarged using standard stretching techniques, the details of the necklace are compressed, leaving a blurry image without any hint of detail or smooth transitions. In contrast, enlargement using AI technology analyzes the original image and creates an entirely new representation of the necklace. AI-powered technology accurately recreates features such as the diamond’s sparkle, the chain’s intricate design, and the overall elegance, allowing the viewer to appreciate the beauty of the necklace without losing quality or detail.
- Quality improvement: AI minimizes noise, artifacts, and other defects that usually occur when enlarging an image. That is, the sharpness of lines and details and the general appearance of the photo are completely preserved. This process is also called image interpolation. For example, you have a grid of colored pixels and decide to enlarge the image. Interpolation literally fills in the empty spaces between these pixels, and the image remains smooth and natural.
- The PicsArt SDK: The SDK automatically detects the current image resolution and identifies the required print resolution. It then leverages the upscale API to adjust the image to the appropriate resolution or density, ensuring it meets the necessary DPI requirements. This process allows users to seamlessly upload an image and receive a suggestion for optimal scaling, making sure the print quality is maintained without manual adjustments.
- This feature improves the printing process and helps users understand the importance of image resolution. The SDK seamlessly integrates this API functionality, allowing developers to use the same advanced scaling capabilities in their apps.
- Automation and scaling: One of the features of the PicsArt Creative APIs is the simple and effective integration of the service into your applications or web services. For companies that constantly work with large volumes of images, this is an opportunity to automate image processing while ensuring stable quality in the flow.
