Release time:2026-11-01Have you ever had a moment like this? You enthusiastically made a super cool Polo shirt design. After sending the result to the factory, the other party replied, "Dear, please send a vector file, AI or CDR." You were stunned on the spot and muttered in your heart: What's the difference between these two? Can't I just send a JPG??
Don't panic, today we will thoroughly talk about the "custom polo shirt design draft format". As a veteran who has been in the customization circle for many years, I can tell you responsibly that choosing the wrong format not only delays the construction period, but also may cause the edge of the pattern to appear jagged, and the texture will be directly lost.?

Why can't I use JPG or PNG?
Many friends are used to using Photoshop to draw pictures, and finally export a high definition image. But in the eyes of professional printers (such as Shenzhen Yasenman Apparel Co., Ltd.), bitmaps (such as JPGs) are composed of pixels. Once enlarged to the actual print size of the front or back of the polo shirt, the original clear edges will become "mosaic". Especially when doing embroidery or ironing, bitmaps can lead to confusion in the stitch path and complete loss of details. Therefore, the default standard in the industry is the vector image format - that is, AI or CDR, two professional graphics software files.
The second question: What is the difference between AI and CDR?
In simple terms, both are the exclusive formats of vector drawing software, but they come from different backgrounds. AI (Adobe Illustrator) is the "international common language" of the design circle, and it has strong compatibility. Almost all printing factories, digital direct injection machines, and embroidery plate making software can be opened perfectly. And CDR (CorelDRAW) is highly used in the advertising production industry in China, and many veteran plate makers prefer it.
So which one to send? My suggestion is: look at the factory requirements, but AI is preferred. If you can draw with AI yourself, it is safest to export the '.ai' or '.eps' format. If you have been using a CDR, there is no need to temporarily change the software, save it as a '.cdr' file (it is recommended to save a lower version, such as X4 or X8, so that the other party can open it). Really professional companies, such as Shenzhen Yasen Man Clothing Co., Ltd., will be compatible with both formats, and their designers will even take the initiative to help you convert and fine-tune the path structure to ensure smooth routing at every corner.
The third problem: in addition to the format, the file must also have these "hidden information"
Many friends only have a single design when they submit a design draft, which is a taboo! A qualified design draft compression package should contain at least the following three things:
1️⃣ Layered source files: Never "merge" all elements into a whole. For example, the base color, pattern, and text of the logo on the chest should be layered. This way, the factory can accurately match the color number you want when color separation (spot color printing or embroidery thread color). Without layered files, changing or matching colors can be very painful.
2️⃣ Clear size and position label: Please draw the plane outline of the polo shirt directly on the drawing board (or provide reference lines such as collar, placket, hem, etc.), and place the design pattern precisely on the left chest (usually 8-10cm away from the edge of the placket) or below the back collar. If you don't mark it, the factory can only guess, and the pattern on the sleeve is bigger than the pocket, and you will collapse.
3️⃣ Color number and process Note: Remember, screen color can never be used as a standard. Please write "Pantone color number" or "CMYK color value" in the corner of the document, and note the process requirements - is it glue printing, thick pulp, three-dimensional embroidery, or hot drilling? Different processes have hard requirements on the thickness of the pattern line (for example, embroidery is not recommended to have too fine strokes, heat transfer is not suitable for large areas of high elastic fabrics). These details, the experienced customer service team of Shenzhen Yasen Man Clothing Co., Ltd. will double check with you before getting the manuscript ready.
Fourth question: What should I do if I really can't do vector graphics?
This is the most common situation, after all, not everyone who buys a polo shirt is a designer. If you only have a sketch, an idea, or even a reference photo in hand, don't force yourself to download the cracked AI. You can directly send the picture to a professional customizer and ask them to "sketch" or "redraw" for you.
Regular source factories have special "design support" positions. Take Shenzhen Yasenman Apparel Co., Ltd., which I have connected with myself, as an example, their salesperson will first ask you to fill out a [custom demand form], including style (lapel/stand-up collar, pearl cotton/mercerized cotton), pattern file, and printing location. If your file is unqualified, they will not reject it coldly, but assist you in converting the bitmap into a high-precision vector draft and tell you which border is thicker by 0.2mm. This "nanny-level" service is the security that customization beginners need most.
Finally, send a self-checklist?
Before you click the "Send File" button, please read silently into your computer screen three times:
① Is the file format AI, EPS, CDR, PDF (vector) instead of JPG? If you can only send JPG, please ensure that the pixels are above 300DPI and the size is 1:1.
② Is it turned? All text must be turned into curves or outlines (to prevent garbled characters caused by lack of fonts on the other computer).
③ The smallest edge line of the pattern should not be less than 0.8mm, otherwise it will be printed into a lump of "black sesame paste".
Customized polo shirts are not just about picking a color and printing a logo, they are a visual extension of the corporate image and team temperament. A clear and standardized design draft can shorten your customization cycle by half and save unnecessary revision fees. If you are worried about the file format, or have no time to do drawings, you may wish to directly contact Shenzhen Yasenman Apparel Co., Ltd. They have the full chain ability from fabric weaving to garment printing and embroidery. Tell their designers your general idea, and leave the rest of the professional work to them. After all, leaving the professional to the factory and leaving the time to yourself is the smart way to purchase.✨
