AI image generation has made it much easier to create original visuals for flyers, posters, invitations, wall art and marketing materials. With the right prompt, you can go from an idea to a complete design in minutes. But an image that looks great on your phone or laptop isn't automatically ready to print.
Getting your image ready to print involves a few extra checks, but you don’t need design experience to get started. This guide takes you through the process, from prompting ChatGPT and adding your image to a Canva template to checking the details and uploading your finished file for printing.
Before you generate your image, think about what you actually want to print. A portrait flyer needs a different composition from a landscape poster, while a square image created for social media may need significant cropping to fit an A size page.
ChatGPT lets you request images in different aspect ratios, so you can start with a shape that's closer to your finished product. For example, A size paper uses a ratio of approximately 1:1.414, meaning a portrait page is about 1.4 times taller than it is wide. If you’re creating an A4 or A5 portrait design, you could include that ratio in your prompt.
Example prompt
Create a portrait promotional image for an A5 printed flyer using an aspect ratio of approximately 1:1.414. Keep the main subject towards the centre and leave generous background space around the outer edges. Leave clear space near the top for a headline. Avoid borders.
For an A size landscape design, simply reverse the ratio.
Example prompt
Create a landscape image for an A3 printed poster using an aspect ratio of approximately 1.414:1. Keep the main subject within the central area and leave generous background space around the edges for cropping.
If you're creating something square, you could request a 1:1 image instead. Getting the ratio right from the beginning can reduce the amount of cropping you'll need later, but it doesn't make the generated image a finished print file. You'll still need to set it up at the correct physical dimensions before ordering.
AI generated images often look strongest when the subject fills the frame. For print, a little more breathing room can be useful.
Your artwork may need to extend beyond the finished edge to create bleed, and small differences in cropping can occur during production. If a face, product, logo or other important detail sits right against the edge of your generated image, you've got much less flexibility when preparing it.
Tell ChatGPT where you'd like the important parts of the image to appear and where you need clear space.
For example:
Create a portrait image for a printed event flyer. Keep the main subjects towards the centre and leave plenty of surrounding background. Leave an uncluttered area in the upper third for a headline and clear space at the bottom for event information.
Before you move your design into Canva, try to get the strongest possible image from ChatGPT. AI generated images are usually viewed on a screen first, where they can look sharp even at relatively modest dimensions. Once that same image is enlarged for print, softer areas, fine details and small text can become more noticeable.
Make it clear to ChatGPT that you intend to print the image and ask it to prioritise clear, well defined details. It's also worth avoiding very small lettering or delicate elements if they're essential to the finished design.
For example:
Create this image for printing. Keep important details clear and well defined, and avoid very small text or fine elements that may lose definition when printed.
You can also include the intended format and aspect ratio in the same prompt so the generated image is closer to the shape of the finished product.
You’ll still need to check that the downloaded image contains enough detail for your chosen print size, which we’ll cover below.
Yes. If ChatGPT has created a complete design you’re happy with, you can place that image into your Canva template without rebuilding every element.
Check the wording carefully first. Make sure names, dates, prices and contact details are correct, and look for unusual lettering or spelling mistakes.
Text within an AI generated image is part of the picture, so it can become softer when enlarged. Adding important wording separately in Canva can give you sharper lettering and make future changes easier.
You could keep the AI image as your background and add headings or contact details over it, removing or covering the original wording first. It’s an optional improvement, rather than something every design needs.
Once you’re happy with your ChatGPT image, download it to your device. Use the downloaded image rather than a screenshot so you keep the detail available in the original file.
Choose a WTTB Canva template that matches the product, size and orientation you want to order, then open it in Canva.
Upload your saved image into Canva and add it to the page. Resize and position it to fit your design, checking that nothing important gets cropped. Avoid stretching it out of proportion, as this can make faces, objects and lettering look distorted.
If you’re using the complete AI design, you can keep the image together. If you’d like to make changes, this is where you can add your own text, logo or contact details as separate Canva elements.
Before moving on, check that you’re using the right template for your order. An A5 flyer design, for example, should be prepared in the A5 flyer template.
An image that looks sharp on your phone can look softer when it’s enlarged for printing. What matters is how many pixels it contains compared with the size you want to print it.
For detailed print viewed up close, aim for 300 DPI at the finished size. As a guide, a portrait image filling the page would need approximately:
These figures cover the finished page size, before adding bleed. If you crop the image, you’ll also have fewer pixels left to fill that space.
To find your image’s pixel dimensions, open the downloaded file’s information or properties on your device and look for its width and height in pixels. Compare these with the size you want to print.
Asking ChatGPT for “300 DPI” doesn’t guarantee that the image will contain enough detail. The downloaded file’s actual pixel dimensions are what count.
Once you’ve placed the image in Canva, look closely at faces, fine details and lettering for blurring, distortion or mistakes. Screen zoom alone won’t confirm print quality, but it can help you spot problems before ordering.
If the image is too small, consider using it at a smaller size within your layout, choosing a smaller printed product or trying the upscaling option below.
Canva has an Upscale tool, available with eligible Canva plans, that's designed to improve low resolution images by making blurry or pixelated imagery appear sharper and clearer. That can be useful if your ChatGPT image needs a little extra help before you use it within a larger design.
It's worth remembering that upscaling isn't a guarantee that any small image can suddenly become suitable for a huge printed product. It can improve the appearance of an image, but there's a limit to how much detail can be recovered or recreated when the original doesn't contain enough information.
If an image needs to be enlarged dramatically, you may get a better result by returning to ChatGPT and generating a stronger version, changing the composition or choosing a different image. The aim isn't necessarily perfection at extreme magnification. It's making sure the image looks good at the size and viewing distance of the product you're actually creating.
AI generated imagery can contain extremely vivid colours, glowing light effects and highly saturated backgrounds that look particularly striking on a screen. Printed colour works differently.
Screens produce colour using RGB light, while printing typically reproduces colour using CMYK inks or toners. Because the two processes create colour differently, your finished print won't necessarily look identical to the version you see on a backlit display.
That doesn't mean you need to avoid bright or colourful AI artwork. It's simply worth knowing that particularly vivid colours may reproduce differently once they're printed.
If colour is an important part of your design, our How Colour Works in Print guide explains RGB, CMYK and the differences between screen and printed colour in more detail.
Bleed is extra artwork that extends beyond the finished edge of your print. It gives us a little room when trimming, helping prevent unwanted white edges.
In Canva, open the File menu, find the view settings and turn on Show print bleed. If your background or image should reach the edge of the finished product, extend it to fill the bleed area too. Simply switching the guide on won’t extend your artwork for you.
Most products need 3mm of bleed on each edge, but check the requirements for your chosen product before exporting.
Keep important text, logos and faces comfortably inside the finished edge, following any safe area guidance supplied with your template. Backgrounds can extend into the bleed, but details you want to keep shouldn’t.
If filling the bleed cuts off something important, try repositioning the image or using a matching background behind it. Avoid stretching the image to force it into place.
Use our Canva Print Checklist to review your size, bleed, safe areas, image quality and colour setup before exporting.
Once your ChatGPT image is positioned, your text and branding are finished and you've completed your checks, you're ready to export the artwork.
For WTTB orders, download your completed Canva design using PDF Print, with crop marks and bleed enabled where required. It's also worth opening the exported PDF before uploading it. Check the artwork one final time and make sure nothing has moved, disappeared or been cropped unexpectedly.
Your workflow can be as simple as:
ChatGPT image → WTTB Canva template → final checks → PDF File → upload with your order
With your PDF checked and saved, you’re ready to order. Choose the WTTB product that matches your template, then select your size, quantity, paper or material, and any available finishing options.
Once you’ve placed your order, upload your PDF using the upload button on the confirmation page. You can also upload it through the Orders section of My Account.
Upload the PDF you exported from Canva, rather than the original ChatGPT image, so you’re supplying the artwork you’ve prepared at the correct size.
Turning your ChatGPT image into print doesn’t need to mean starting again. With the right template, a few practical checks and a correctly exported PDF, you can take your design from screen to something you can hold.
Choose your WTTB Canva template to get started, and use our Canva Print Checklist before placing your order.
