Q & A

  • What is the main topic of the video?

    -The main topic of the video is upscaling AI-generated images for print-on-demand, specifically for T-shirt designs.

  • Why is upscaling necessary for AI images before printing?

    -Upscaling is necessary because most AI images come in a smaller size (usually 1024 x 1024), which is not sufficient for print-on-demand services that require larger dimensions, such as 4500 x 5400 pixels for Amazon Merch.

  • What is vectorizing, and how does it differ from upscaling?

    -Vectorizing is the process of converting an image into a vector format, which allows for clean, sharp edges and infinite scaling without pixelation. Upscaling, on the other hand, adds pixels to the image to increase its size, making it smoother and more suitable for printing.

  • What are the two primary methods discussed in the video for solving the problem of getting AI images to the required size for printing?

    -The two primary methods discussed are upscaling and vectorizing. Upscaling adds pixels to the image, while vectorizing converts the image into a vector format with clean edges.

  • What is the target size mentioned in the video for Amazon Merch print-on-demand?

    -The target size mentioned for Amazon Merch print-on-demand is 4500 x 5400 pixels.

  • How does the video demonstrate the pixelation issue with AI images when scaled up directly?

    -The video demonstrates the pixelation issue by showing an AI image that is stretched from 1024 x 1024 to 4500 x 5400 pixels in Affinity Designer, resulting in visible, enlarged pixels and a jagged edge when zoomed in.

  • What is the first free online upscaler mentioned in the video, and what is its limitation with AI images?

    -The first free online upscaler mentioned is Its limitation with AI images is that it does not accept WebP files, which is the format that Chat GPT saves images in, requiring users to convert the images to PNG or JPEG before using the service.

  • What is the advantage of using an upscaler like 'I love IMG' as shown in the video?

    -The advantage of using 'I love IMG' is that it can upscale images up to 4X or even 6X times the original size quickly and effectively, resulting in a cleaner, more detailed image suitable for printing without jagged edges or pixelation.

  • How does the video address the issue of limitations with different upscalers?

    -The video addresses the issue by showcasing various upscalers, discussing their limitations, and offering workarounds where possible, such as cropping an image to fit within the size limitations of Pixel Cut or using multiple applications to achieve the desired result.

  • What is the final recommendation in the video regarding upscaling versus vectorizing for AI-generated images?

    -The video suggests that while vectorizing provides clean, sharp edges, upscaling can be a good alternative, especially when it comes to preserving gradients and details that might get distorted during vectorization. The choice between upscaling and vectorizing depends on the specific needs of the design and the desired outcome.

  • What other tools or services are mentioned in the video for upscaling AI images?

    -Other tools and services mentioned include Dgb LOL, Pixel Cut, Leonardo, Mid Journey, and Canva's Pixel Perfect app. Each has its own set of features, limitations, and pricing structures.



๐Ÿ” Introduction to Upscaling for Print on Demand

Juna from Detour Shirts introduces the concept of upscaling AI-generated images for print on demand services like Amazon Merch. The necessity for upscaling stems from the standard image size produced by AI, typically 1024x1024, which is smaller than the required dimensions for T-shirt printing (4500x5400). Through a demonstration in Affinity Designer, Juna illustrates the loss of image quality that occurs when simply stretching an image to fit the necessary dimensions. The video promises to explore seven free online tools for effective upscaling, emphasizing the goal of achieving cleaner, non-pixelated images suitable for high-quality print results.


๐ŸŒ Exploring Free Online Upscaling Tools

Juna proceeds to test various free online upscaling tools to address the quality degradation issue when enlarging AI-generated images. The journey begins with an unsuccessful attempt to use Upscale's AI due to format limitations with WEBP files, leading to a workaround involving Photo P for format conversion. The focus then shifts to comparing the effects of different upscaling ratios (2x, 4x, and even 6x) on image quality. Through these experiments, Juna highlights the improvements in image clarity at higher scales, particularly noting the reduced pixelation that makes the designs more suitable for print on demand. The process underscores the importance of selecting the right tool for optimal upscaling results.

Upscaling refers to the process of increasing the resolution of an image, making it larger while attempting to maintain or improve its quality. In the context of the video, upscaling is essential for preparing AI-generated images for print-on-demand services, such as t-shirt printing, where higher resolution images are required to ensure the print quality is not pixelated or blurry.

๐Ÿ’กAffinity Designer

Affinity Designer is a graphic design software application used in the video to demonstrate the upscaling process. It is utilized to show the transformation of a low-resolution AI-generated image into a high-resolution format suitable for printing. The software's features, such as the ability to manipulate image size and observe the effects of upscaling, are highlighted in the tutorial.


Vectorizing is the process of converting images into vector graphics, which are composed of straight lines and curves rather than pixels. This technique is mentioned in the video as an alternative to upscaling for preparing images for print. Vectorized images can be scaled without losing quality, making them ideal for various sizes and formats.

๐Ÿ’กAI Image

An AI image refers to a visual created by artificial intelligence, such as through AI-generated design tools like Chat GPT. These images often start at a standard resolution of 1024 x 1024 pixels. In the video, the host discusses the need to upscale these AI images to meet the requirements for print-on-demand services, where larger, high-resolution images are necessary.


Print-on-demand is a service that allows for products, such as t-shirts, to be printed with custom designs only when an order is received. This process eliminates the need for holding inventory and allows for a wide variety of designs to be offered. The video focuses on preparing AI-generated images for use in print-on-demand, emphasizing the importance of image resolution for high-quality prints.


Resolution refers to the number of pixels in an image, which determines its size and detail. A higher resolution means more pixels and thus more detail, which is crucial for images intended for printing. The video script discusses the need to increase the resolution of AI-generated images from the standard 1024 x 1024 pixels to meet the requirements for print-on-demand services.


WebP is a modern image format that provides good compression while maintaining high visual quality. In the video, the host mentions that the AI-generated images initially saved as WebP files need to be converted to formats like PNG or JPEG for use in certain upscaling tools, as some services do not accept WebP files directly.


Pixelation is a visual defect that occurs when individual pixels become visible, often due to low resolution or improper scaling. In the context of the video, the host demonstrates the pixelation effect when stretching a low-resolution image in Affinity Designer, emphasizing the need for upscaling to avoid this issue and achieve a clean, crisp print quality.

๐Ÿ’กChat GPT

Chat GPT is an AI language model developed by OpenAI, known for generating human-like text. In the video, it is mentioned as a tool for creating AI-generated images, which are then used as a starting point for the upscaling process. The host uses these images to illustrate the differences in quality before and after upscaling.
