Go for the Sharpest Image on Your Survey Form
One of the best ways to give your survey form a polished, professional look is by adding a logo or other graphic image. When adding a logo or graphic, it is very important to use the right kind and quality of image. A fuzzy, low resolution image will produce the opposite result, giving your form an unprofessional look and feel.
Join the Resolution Revolution!
The quality of graphic images depends on the image resolution, or the number of dots per inch (dpi). The more "dots" the better the image quality, so it is important to start with an image with more dots per inch. Resizing or scaling your graphic image will likely degrade the quality appearance of your logo or graphic.
As you can see from the examples above, these images get fuzzier as they are enlarged. You can always zoom in on the image on your computer screen to get a better idea of the quality of your image. (An easy way to do this is to hold the Control Key down on your keyboard and hit the "+" key several times. To zoom out, hold down the Control Key and hit the "-"symbol.) If an image looks fuzzy when you zoom in, chances are it will look fuzzy when inserted onto a printed form.
OMR Form Printing–What Graphics Format Works?
If you are creating your own OMR survey form using a software such as Data Blocks Magenta or Scantron's DesignExpert™, you can add images or logos to your design as long as the image is in a bitmap image format. In the printing industry, there are two basic types of graphic images. The first type is a bitmap, also known as a "raster" image. A bitmap could be one of many file types (.bmp, .jpeg, .gif, etc.) Bitmap images are:
Made up of pixels in a grid. Tiny dots of color come together to form the image. When you zoom in on a bitmap image, you can see the dots as squares of color hooked together.
Always square or rectangular. If your logo is an oval shape, it will be an oval within a rectangular frame when it is in bitmap image format.
A solid block of color (or white). No part of a bitmap image is transparent or see through. For printing purposes, a bitmap cannot be color separated. This means it must be printed in one color (i.e., all black, all red) or converted to grayscale.
The other format of graphic image used in the print industry is a vector image. A vector image is made up of individual shapes and/or text. Each shape in a vector image can be edited independently. A vector format image will usually have an .eps file extension. Vector images are:
Made up of individual elements, such as shapes, lines and text. Each element can be edited by without affecting other elements.
Can be any shape or size and is not resolution dependent. This format of graphic is always very sharp looking and is not confined to a rectangular shape.
Most important from a printer's perspective, a vector or .eps image can be color separated for printing. Elements can be assigned exact and multiple colors.
Vector images can be converted to bitmap format for use on web surveys or for use in form design software.
Getting Graphic–Summing it Up
In my opinion, a bad or fuzzy graphic image should never appear on your form! Only add images that are high quality and that enhance the appearance and effectiveness of the document. Most OMR form design software has severe limitations when it comes to adding good quality graphics to the forms you design. Always use the highest resolution graphic image you can get your hands on. For even better results, have your OMR form printing company help. A printing professional can use graphics software to really make your survey form sing!
