由人工智能和领英社区提供技术支持

High-dpi displays, such as Retina screens or 4K monitors, offer sharper and more detailed images than standard displays. However, they also pose some challenges for graphic designers who want to optimize their images for web and print. How can you ensure that your images look crisp and clear on high-dpi displays without compromising on file size, loading speed, or compatibility? Here are some best practices to follow.

本文章的要点总结

Leverage image optimization tools:

To keep images crisp on high-dpi displays, use online optimization services. They compress images without losing quality, ensuring your graphics are both clear and load quickly.
Assign color profiles:

Color accuracy is key on high-dpi screens. Assign an ICC (International Color Consortium) profile to your images for consistent and accurate color display across various devices.

1 Choose the right format

Different image formats have different advantages and disadvantages when it comes to high-dpi displays. Generally, you want to use vector graphics (such as SVG or PDF) for logos, icons, and illustrations, as they can scale infinitely without losing quality. For photos and complex images, you want to use raster graphics (such as JPEG or PNG), as they can preserve colors and details better. However, you also need to consider the compression, transparency, and animation features of each format, and choose the one that suits your purpose and audience.

Depending on the needs, is it for prints or digital uses, or other purposes, we cannot use formats that are not meant to be for the required purposes, as an example using raster image for prints that requires vector images or graphics will create a guaranteed pixel explosion on the output and quality of prints will be affected. With regards to compression for file handling or working with the formats we can opt in optimizing each image files depending on the needs by using methods and various techniques of compression and optimization.

2 Use responsive images

Responsive images are images that adapt to the screen size and resolution of the device they are displayed on. They can help you optimize your images for high-dpi displays by serving different versions of the same image depending on the pixel density, viewport width, or other factors. You can use HTML attributes such as srcset and sizes, or CSS properties such as image-set and media queries, to implement responsive images on your web pages. This way, you can avoid sending unnecessarily large or small images to your users, and improve the performance and user experience of your website.

The compression of images should be optimized for file size reduction without sacrificing quality. You can find a balance between image quality and file size with the use of programs like Adobe Photoshop, ImageOptim, and online resources like TinyPNG. The stages by file can be reduced in Photoshop Cloud. file> save for web Options Most current web browsers support WebP, a new image format that offers high-quality compression. For greater compression and quality on high-DPI devices, think about using WebP pictures.

3 Optimize your images

Optimizing your images means reducing their file size without sacrificing their quality. This can help you speed up your website loading time, save bandwidth, and improve your SEO ranking. There are many tools and techniques that can help you optimize your images for high-dpi displays, such as cropping, resizing, compressing, converting, or using progressive loading. You can also use online services or plugins that can automatically optimize your images for you. However, you should always test your images before and after optimization, and make sure that they still look good on high-dpi displays.

One thing I've found useful is that people nowadays can get help from differen ai websites to optimize their images with the excessive file size I always google it and find bunch of best websites to do such works. The best tool to shrink the image size I've been using is Tinypng website that offers the best shrinkage in file size without any loss of quality. Moreover if you use adobe photoshop you can save images by using export > save for web, it is the most time saving work.

4 Use retina-ready icons and fonts

Icons and fonts are essential elements of graphic design, and they can also benefit from high-dpi displays. However, not all icons and fonts are retina-ready, meaning that they can look blurry or pixelated on high-dpi displays. To avoid this, you should use icons and fonts that are designed for high-dpi displays, or that can scale well with different resolutions. You can use icon fonts, SVG icons, or font icons that can render smoothly on any screen. You can also use web fonts, such as Google Fonts or Adobe Fonts, that can deliver high-quality fonts to your website.

5 Test your images

The final and most important step of optimizing your images for high-dpi displays is testing them on different devices and browsers. You should check how your images look on various screen sizes, resolutions, and pixel densities, and make sure that they are consistent and coherent across different platforms. You should also test how your images affect your website speed, performance, and usability, and make adjustments if needed. You can use tools such as BrowserStack, Google PageSpeed Insights, or Lighthouse to test your images and get feedback and suggestions on how to improve them.

Un aspect important de l'affichage des images pour les écrans est de leur assigner un profil couleur (ICC color profile) qui permettra leur affichage correct au niveau colorimétrique. La plupart des navigateurs Web prennent en compte ces profils d'images, ce qui est un plus en terme de qualité d'affichage.

Good working practice is to always keep your original, make a copy and size appropriately. When file saving, this would depend on the end use of your image. PNGs very good for colour. However, I have used gif's a lot, and learned if you have minimal colours, such as 3 colour logo, you can pick those 3 colours suitably be editing the colour in the colour table and really reduce the file size, when you compare to the general export options, with 256 colours.
