Image Formats –
Have you ever wondered when you should use a JPG rather of a PNG? Or perhaps you are just trying to figure out which program opens an INDD.
Unless you are a graphic developer by training( like me), chances are you’ve noway demanded to understand effects like what separates a TIF from a PDF or a PSD. While the large variety of image formats may feel inviting, there’s a system to the madness.
We have put together a useful figure to help you understand the difference between each train format, and when they’re applicable to use.

Vector vs Raster –
First effects first What’s the difference between vector and raster?
Raster Image Files
Every print you find online or in print is a raster image. Pixels have a defined proportion grounded on their resolution( high or low), and when the pixels are stretched to fill space they weren’t firstly intended to fit, they come malformed, performing in vague or unclear images.
In order to retain pixel quality, you can not resize raster images without compromising their resolution. As a result, it’s important to flash back to save raster lines at the exact confines demanded for the operation.
Vector Image Files
Vector images are far more flexible. They’re constructed using commensurable formulas rather than pixels. EPS, AI and PDF are perfect for creating plates that bear frequent resizing. Your totem and brand plates should have been created as a vector, and you should always have a master train on hand. The real beauty of vectors lies in their capability to be sized as small as a postage stamp, or large enough to fit on an 18- wheeler!
still, then is a little trick for you Call the company that published your business cards or the seller that exaggerated your totem on a shirt, If you are not sure whether you have a vector interpretation of your totem. frequently they’ll have a vector train of your totem that they can shoot to you for your records.

High Resolution vs Low Resolution
Have you heard your developer talk about DPI or PPI? DPI stands for” blotches per inch” and PPI translates to” pixels per inch.” These units of measure are essential for determining if the viscosity of pixels in an image is applicable for the operation you’re using.
The biggest thing to note when determining what DPI or PPI you bear is if you’re using an image for print or web. Websites display images at 72dpi, which is low resolution; still images at this resolution look really crisp on the web. This isn’t the case for print. Stylish practices for publishing an image will bear it to be no lower than 300dpi.
Do not try to trick the system.
Pulling an image off of the web and trying to get it to fit the confines of your print design just will not work. You’ll end up with a pixelated image that appears stretched and distorted.
JPEG( or JPG)-common Photographic Experts Group
JPEGs might be the most common train type you run across on the web, and further than likely the kind of image that’s in your company’s MS Word interpretation of its letterhead. JPEGs are known for their” lossy” contraction, meaning that the quality of the image decreases as the train size decreases.
You can use JPEGs for systems on the web, in Microsoft Office documents, or for systems that bear printing at a high resolution. Paying attention to the resolution and train size with JPEGs is essential in order to produce a nice- looking design.

JPG vs JPEG
There’s no difference between the. jpg and. jpeg filename extensions. Anyhow of how you name your train, it’s still the same format and will bear the same way.
The only reason that the two extensions live for the same format is because. jpeg was docked to. jpg to accommodate the three- character limit in early performances of Windows. While there’s no similar demand moment,. jpg remains the standard and dereliction on numerous image software programs.
