ART FILE EXPLANATIONS & REQUIREMENTS
PDF- Portable Document Format
Vector - Transparency- NOT ALWAYS DESIGNED FOR PRINTING
While EPS and AI files require specialized preview software, PDFs were intended to be viewable regardless of software, hardware, or operating system. If it’s the only format you have of your logo, sometimes it can be used for print and digital applications if it has the layers and was not flattened. The original goal of a PDF was to preserve and protect the content and layout of a document - no matter what platform or computer program it is viewed on. This is why PDFs are hard to edit and sometimes even extracting information from them is a challenge. While some PDF’s may be able to be used for Hi-Res printing, it is not always the case. You can’t determine if the PDF can be edited until opened in Adobe Illustrator or similar graphic software.
EPS- Encapsulated PostScript
Vector - Transparency- BEST FILE FOR PRINTING
EPS files are transparent, scalable, and editable if you have the right software. It also has unlimited color capacity. It keeps the logo file from dictating the layout of the print piece due to its size and background. The vector images contain bitmaps that tell each pixel in the image what size and color they should be so that you can make an image into nearly any size without restriction or possible pixelation. EPS files have the ability to be resized without loss of quality, and will also be able to be easily edited and manipulated, making them perfect for not only editing but printing. Colors and layers can be easily separated so its the best format for screen printing. Note- some people may open a PDF or flattened file in Adobe Illustrator and save it as an EPS File. EPS files only work if the original file was created in Adobe Illustrator.
AI- Adobe Illustrator Artwork
Vector- Transparent- BEST FILE FOR PRINTING
As opposed to the open standard formats above, AI is a proprietary file format by Adobe. Unless the file is saved with PDF compatibility, you can only view an AI with the appropriate Adobe software. That said, apparel printers particularly like receiving artwork in this format. AI is editable, scalable, and transparent. An EPS file can do anything an AI can do, but, as Adobe expands ease of transfer within its software programs, AIs are becoming more viable as the preferred logo format.
CANVA Art
NOT ALWAYS DESIGNED FOR PRINTING
If you use Canva please save your design as an .SVG file, but please note Canva files typically don't convert fully to a vector file. SVG files are vector, and can sometimes be used to make final print ready art, but if the design incorporates a .jpg or .png image placed in it to make part of the logo, that part of the file will not be editable or convert to a vector format.
DIFFERENCE BETWEEN .JPG AND .PNG FILES AND WHY THEY WONT WORK FOR PRINTING, SCREENPRINT OR EMBROIDERY PROJECTS
JPG- Joint Photographic Experts Group
Raster - No transparency Best for web/digital
The jpg, or jpeg, is arguably the most commonly used image file format. It was designed by photographers for use with photographs and photo-like images, so it works best for images with smooth transitions between colors. As a glossy compression format it’s a poor choice for graphics with sharp contrast between pixels. You shouldn’t try to edit a JPG because you’ll lose quality every time you decompress and recompress the file. JPGs are useful when a small file size is crucial, like in your email signature. Because JPEGs compress image data, its file sizes tend to be relatively small. This means that it’s a convenient way to share digital images over the web and email. But JPEGs use lossy compression, which means that each time you save your file, you lose a little bit of image data, which can affect quality. JPEGs can’t be separated into components because they compress all content into a single layer, so they cant be used for separating images for printing files.
PNG- Portable Network Graphics
Raster - Transparency- Best for web/digital
PNG was developed to avoid a lawsuit regarding the licensing of GIF technology back in 1994. While it typically has a larger file size than a JPG, it can compress further when storing images containing text, line art, and areas of solid color. The transparency is infinitely useful in web applications and the lossless data compression results in cleaner, sharper images. That said, PNGs are raster les so you’ll see pixels if you try to increase the image size. PNG also doesn’t support color spaces for print as they were designed with the web in mind. Because of this, they don’t support CMYK color modes, so they do not scale up or work for printing.
