How to Resize Images for Print

When you are looking to print a graphic — perhaps as a sticker or custom t-shirt — one of the first things to do will be to resize it to the proper dimensions. But you'll also need to make sure it retains good resolution. Without proper resolution, it's just not possible to get a quality-looking product.

Resizing a large image into a small one is a fairly simple process that most image editors will cover, including Photoshop and many different online-based image apps. But what to do if you're stuck with a low-quality file that you want to enhance? If you can't find a higher-resolution version of it, one way out would be to upscale it. Below, we'll look at how you can do a basic resizing in the first case, and how, if your file is undersized or low quality, Upscale by Sticker Mule helps you get it ready for printing.

Understanding image resolution for printing

Here perhaps we should recap just what image resolution is. In a few words, it represents how much detail your image has, and hence how much it can be expanded. For digital files, that is usually represented in pixels (short for "picture elements"). The higher your picture's PPI (pixel per inch) ratio, the more you'll be able to expand it.

For printing, a different measurement is commonly used: DPI, or dots per inch. It’s the number of dots and spaces a printer produces within each inch of printed material. Higher DPIs mean a higher quality look on your printouts. Typical print sizes are 300 DPI for content such as leaflets, stickers, and labels, and 150 DPI for larger printouts such as posters and wall graphics, where the viewer will stand farther away from the print.

Resizing images with Photoshop

If all you need to do is resize your picture because it's too large to fit your editing canvas or the file is too heavy to upload, you'll find it an easy enough procedure:

1. Open your image file on Photoshop

2. Click Image > Image size. A dialog box will open.

3. Adjust the image's dimensions in pixels on the width and height fields, or simply enter a percentage of the current size.

4. If you prefer to use a measurement other than pixels, you can also do so in the same dialog box — inches, centimeters or millimeters, among other options.

What if you want to resize your picture while retaining the original one, with the original resolution? That's easy, too — just use the export function:

1. With your file open on Photoshop, click File > Export.

2. Adjust your new file's dimensions (pixels or percentages).

3. Select the format for the new image you are creating (JPEG, PNG, etc.) and click OK.

4. And that's it — now you'll have created a second, smaller file for your current use case, while at the same time keeping the original one safe and sound.

Using free tools to resize your images

If you don't have a Photoshop account or your laptop starts sounding like a malfunctioning rocket when you try to run it, you can try using one of a myriad of free online tools. Here are a couple of them.

Image Resizer

Image Resizer is a nifty and easy to use tool. Just open their homepage, upload the image you want to resize and enter the new dimensions. Once again, you can do it either in percentage terms or by entering the new size directly in pixels. Just make sure you keep the original width/height ratio intact.

Once that is done, click Resize image and, after a few seconds, you'll be presented with a ready-to-download, resized version of your file. You'll also be able to re-edit it, convert it to PDF, or compress it to a .ZIP file.

Adobe Resizer

You don't need to have Photoshop to benefit from an Adobe resizing service. That's just what their online resizing service is for. To use the free Adobe image resizer:

1. Go to the Adobe Free Image Resizer page.

2. Click Upload your photo.

3. Select the file in question on your computer.

4. Once the file is uploaded, enter its new dimensions and click Resize.

5. Your file will soon be ready for download. Before downloading, you'll also be able to choose new dimensions for your file according to standard sizes such as Instagram story, landscape, portrait, and square.

As resizing is a fairly simple operation, any of the above options should be enough for your needs. Both Image Resizer and the Adobe solution are free and don't require creating an account. However, we found that the Image Resizer is best for slower-working devices.

Finally, remember the solution to your resizing needs may be literally in the palm of your hands. Most modern Android and iOS smartphones come with image editing software that works great for simpler operations such as resizing, so you can likely generate your new image file on the go.

Enhancing image size without losing quality with Upscale by Sticker Mule

What if you need to resize an image upwards — that is, your file is too small for your printing needs? Run it through any of the above options, and you'll find yourself looking at a larger, but pixelated and low-resolution image. In fact, the Adobe tool will sometimes tell you straight off that your image is too small for the selected size.

So yes, for enhancing your image size you'll need something a little more advanced than any old picture resizer. Allow us to present our very own solution: Upscale, by Sticker Mule.

What does Upscale do?

Upscale leverages the power of AI algorithms to increase the number of pixels in your image. As it expands your image, it also fills in the missing pixels, avoiding the granulated look you would get otherwise.

Upscale is completely free to use. It also boasts a pretty simple and intuitive interface. Try it out yourself:

1. Go to the Upscale main page

2. Upload your image (or images, as you can also run a bulk upscaling)

3. Select the type of image — photo or artwork —, or, if unsure which to choose, leave it in Auto

4. Select the desired upscaling scale — 2x, 4x or even 8x.

5. Click Start processing and hold on tight. Upscaling one or two images should be fast enough, but if you're doing that with a whole bunch of them, you might want to check the Email me when complete box and go about your business. Just don't close your browser tab!

6. When your files are ready, you'll be shown their new size in pixels, in comparison to the original one. Now click the download button and you're all set.

7. [Optional]. If you want to order your prints directly from our website, simply select the desired product, below your upscaling results — stickers, coasters, labels, keychains, or anything else from our store. Enter the quantity and size and order in one click. It's as simple as that!

As a caveat, remember even the best apps have their limitations, and Upscale is no exception. If the original file is minuscule and barely has a fistful of pixels to show, you should adjust your expectations for the result accordingly.

Resizing and re-dimensioning are key steps if you want to ensure the best possible results for your custom printed products. And happily, as you can see from the above examples, it's also a pretty straightforward process. So give the above browser-based options a go and see what works best for your use case. You'll soon have a properly sized version of your graphic, ready to print.

Understanding Minimums in Screen Printing: What You Need to Know

Screen printing is a popular and versatile method of printing used for a wide range of applications, from custom t-shirts to promotional products. If you're considering screen printing for your project, you may have come across the term "minimums." In this blog post, we'll delve into the concept of minimums in screen printing and explain what you need to know to navigate this aspect of the printing process.

Understanding Minimums:
In the context of screen printing, minimums refer to the minimum quantity of items that a printer requires for a specific design or order. Printers often impose minimums to ensure that the production process is efficient and cost-effective. These minimums can vary depending on factors such as the complexity of the design, the type of item being printed, and the capabilities of the printing facility.

There are several reasons why screen printing minimums exist:

1. Set-Up Costs: The screen printing process involves creating custom screens for each color in the design, preparing the printing equipment, and aligning the screens accurately. These set-up tasks require time, effort, and materials. By setting minimums, printers can distribute these costs over a larger quantity of items, making the process economically viable.

2. Efficiency: Screen printing is a sequential process, where each color in the design is applied separately. To optimize production time and resources, it is often more efficient to print multiple items at once. Minimums help printers maintain a workflow that maximizes efficiency and reduces downtime.

3. Profitability: Printing businesses need to cover their costs and make a profit to stay sustainable. By setting minimums, printers can ensure that each order meets a certain threshold of profitability necessary to run their operations successfully.

Here are a few tips to help you navigate minimums in screen printing:

1. Communication: When considering screen printing for your project, it's essential to research potential printing companies and their minimum requirements. Reach out to the printers directly and discuss your specific needs. Clear communication will help you understand the minimums they have in place and explore any potential flexibility based on your requirements.

2. Cost Considerations: Minimums are often tied to the cost per item. As the quantity increases, the per-item cost tends to decrease. Evaluate your budget and determine the optimal quantity that strikes a balance between affordability and meeting the printer's minimums.

3. Group Orders: If you don't require a large number of items yourself, consider joining forces with friends, colleagues, or community groups who may have similar printing needs. By combining orders, you can collectively reach the printer's minimums and share the cost, making it more feasible for everyone involved.

Minimums in screen printing serve a practical purpose, helping printers streamline their production process and maintain profitability. By understanding the reasons behind minimums and effectively communicating with printing companies, you can navigate this aspect of screen printing and find the right balance between quantity, cost, and quality for your specific project.

Learn Differences Between Printing Processes

When ordering t-shirts, it's important to understand the different printing methods. Our website and Etsy offer screen-printed designs using plastisol ink, while Amazon purchases come with DTG printing. Our custom flags and tents are created through sublimated printing. What does this mean? Screen printing, heat press, vinyl, DTG (Direct-to-Garment), and sublimation are all different printing methods, each with its own advantages and considerations.

1. Durability: Screen printing often provides excellent durability and long-lasting prints. The ink used in screen printing is typically thicker and more robust, making it more resistant to fading, cracking, or peeling over time, especially when compared to heat press and vinyl transfers.

2. Vibrant Colors and Opaqueness: Screen printing allows for the use of vibrant and opaque colors. The ability to apply multiple layers of ink during the printing process produces vibrant and eye-catching designs, even on dark-colored garments. In comparison, heat press and vinyl transfers may have limitations in color vibrancy and opacity.

3. Cost-Effective for Large Orders: Screen printing becomes cost-effective when producing large quantities of printed items. Once the screens are set up, printing multiple items becomes relatively efficient, making it a preferred choice for businesses that require a high volume of printed products. Heat press, vinyl, DTG, and sublimation printing may have higher costs per unit for larger orders.

4. Versatility: Screen printing can be performed on various surfaces, including fabrics, paper, plastics, and wood, making it suitable for a wide range of applications. Heat press and vinyl transfers are primarily used on fabrics, while DTG and sublimation printing are more specialized for fabric applications.

5. Customization Options: Screen printing offers a wide range of customization options, including the use of special inks (e.g., metallic or glow-in-the-dark inks), specialty finishes (e.g., foil or flock), and textured effects. This flexibility allows for unique and creative designs. While heat press and vinyl transfers offer some customization options, they may have limitations in terms of effects and finishes. DTG and sublimation printing also offer customization options, but they may have limitations in terms of special effects and the type of fabrics they can be used on.

It's important to note that each printing method has its own strengths and weaknesses, and the better option depends on specific requirements, such as desired print quality, quantity, fabric/material, complexity of the design, budget, and available equipment. It's always recommended to consider these factors and discuss with us or your printing professional to determine the most suitable method for your specific needs.
