Everything You Need To Know About Large Format Color Scanners
Scanners are devices that convert objects, photos and documents into digital images. Most commonly the scanner is connected to a computer and the digital image, converted by the scanner, is transferred into computer. The image may or may not be edited in the computer and then it may be emailed, faxed or simply be kept as a record according to what the owner wants to do with them.
Specifications
Various specifications of scanners are there. These are mainly image sensor type, color or monochromatic scanning, optical resolution and speed. A scanner with a high quality image sensor will offer more shades, better color fidelity and sharper image. Color scanners offer better resembling images.
Optical resolution is the true measure of how well a scanner can see a document. Measured in ‘dpi', optical resolution between 200 and 400 offers standard quality, while that being higher than 400 dpi produces an excellent image. Lastly there is one of the most important factors about the image size that decides the image width of a scanner.
Other specifications can include energy star ratings and software and file formats offered and even weight.
Types
Scanners may come in a variety of types. The most common types of scanners are Drum type scanners, Flatbed type scanners, Film type scanners and Hand type scanners. There are also black-n-white and color scanners available.
As indicated by the names, the former is able to produce only black and white colors while the later will produce a color image. The first age color scanners were realized only by three colors: red, green and blue (the RGB system). There are also CCD (charged couple device) and CIS (contact image sensor) scanners.
These are categories based on image sensors. There are large or small format scanners, too. Large format color scanners are certainly the best of the lot. Historically the first invented scanners were drum type and the most popular is flatbed type.
Despite all these, there remains another viewpoint of differentiating between scanner types. The types are: automatic feed scanners and sheet fed scanners.
Automatic vs. Sheet fed scanners
In an automatic feed scanner the document is scanned efficiently even if they are not put in the scanning tray by manual technique; one after another, as opposed to sheet fed ones. An automatic scanner detects whether a document page is great or small, color or monochromatic and they don't even need to be supplied with arranged documents. The latest quality automatic large format color scanner works far more efficiently when compared to sheet fed ones, where pages need to insert one after one.
Large format color scanners are truly amazing. Spending around $20000-$25000 for one may result in lifelong ease, comfort and increased work efficiency and speed.

What are Different File Formats and What are They Used For?
.tif-------------------------------------------------------------------------------- Tif file (CMYK Color) 300 dpi high resolution (dpi means dots per inch. This is how the image is made up if viewed under a microscope) The tif file is for printing on a lithographic printing press. The CMYK color stands for the four colors that are used in "Process Printing". Cyan, Magenta, Yellow and the K actually stands for Black. This file format is often requested by print shops. This is one of many file formats that a printer can request. If you can open this file format on your PC you will often see that the colors are totally different to the other logo files we send you. This is because your computer monitor and often your home/office printer too uses RGB color. RGB color stands for Red, Green, Blue. Your PC does not have the correct filters to read CMYK color. This is entirely normal and when printed on a lithographic printing press the colors will print correct. (Because a lithographic printing press can print many more variations of the color spectrum you may notice a slight difference in the end product compared to what you would be able to print on a home office printer). It is always best in the case of a consistent corporate identity to use a color matching system like Pantone. You will find a color matching book to view at your local printer. Perfect for: Professional printing. Home/Office printing that supports CMYK color.
.jpg---------------------------------------- JPG files (3 sizes = Normal, Medium and Small) or JPEG as it is often referred to (RGB Color) - 300dpi. These file types are all used for home/office printing in applications like Word or PowerPoint (you import the image into your document) or for web site images in FrontPage or more professional web site editing programs (html editors) like DreamWeaver or GoLive. The resolution of these files is 300dpi which in printing terms is high resolution. We can give you several sizes because although it is possible to make your own sizes using the source file (eps file) few people in reality have the tools to do this. The sizes we send are usually sufficient for most things you want to do personally and if you do need anything else you can get the help of a designer with the correct tools to create other sizes as you see fit. Perfect for: Home/Office printing. Web Design Importing in to Microsoft Office applications like Word, PowerPoint, Excel, Access etc.
.jpg-------------------------------------------------------------------------------- JPG file (Grayscale) 300dpi. This file type is provided so that you can seek trademark status for your logo. Most trademark organizations will only accept images that are in grayscale. Perfect for: Trademark application. Home/Office printing. Web Design Importing in to Microsoft Office Applications like Word, PowerPoint, Excel, Access etc.
.psd-------------------------------------------------------------------------------- PSD file (RGB) 300 dpi. This file format is used by professional designers and is the native file format of Adobe Photoshop. You need Adobe Photoshop to open this file type. We can supply these with a transparent background too, as needed, so it could be used by a professional web designer. Many people mistakenly think the PSD file is your editable supplied source file. This is not true for logo design. For a logo to be used across a large spectrum of uses and applications it is created as an EPS/vector file. Vector files can be resized using the right software without loss of quality. Your PSD file can also be used for home/office printing if you have Adobe Photoshop. I repeat. In the case of logo design, this file type is NOT the master file. Perfect for: Home/Office printing. (Requires Adobe Photoshop. Lite version available on many new PCs as standard) Web Design.

.eps--------------------------------------------------------------------------- EPS file (CMYK Color) This is your fully editable master file that all the other file types are created from. You need specialist software to work with this file called Adobe Illustrator. The eps file is fully editable with the fonts flattened. We flatten the fonts because fonts are just like software and to own a font you must buy the license. If we did not flatten the font, then you would need to buy a copy of the font as well. You are of course free to do that yourself. There are many good font sites on the web but we always recommend Fonts.com The eps file is a vector file. All the other file types we send typ[ically send our clients are what is called raster files. Raster files are made up of tiny dots, clearly visible under a microscope. This means that when enlarged in size or reduced significantly in size, raster type files will lose quality. Vector files on the other hand do not suffer from this loss of quality because the image software uses a mathematical technique called vectoring to create the image - basically, they have seemingly infinite edges. The eps vector file can be reduced and enlarged using the correct software without any loss of quality. This file format is also used by the majority of professional printers. Perfect for: Professional Printing. (Requires Adobe Illustrator the industry standard for professional printers) Graphic Design. (Requires Adobe Illustrator the industry standard for graphic designers)
.ai-------------------------------------------------------------------------------- AI File (CMYK Color) Fully editable stationery design master file. Professional logo designers use vector drawing tools like Adobe Illustrator to create logo designs and not raster drawing tools like Adobe Photoshop. We also use Adobe Illustrator for stationery design as that is the industry standard for printers. Perfect for: Professional Printing. (Requires Adobe Illustrator the industry standard for professional printers) Graphic Design. (Requires Adobe Illustrator the industry standard for graphic designers) Standard Transparent File Formats:Many clients are surprised when viewing the design choices that we send that the JPG logo files do not have transparent backgrounds. The reason for this is that only certain file formats can support transparency. JPG files can not. We can, however, supply a couple of transparent file formats with your finished logo package. These formats are the PSD file and the eps file. Both these formats however require special software to work with. The PSD requires Adobe Photoshop and the eps requires Adobe Illustrator. PSD (RGB Color) - 300 dpi. This file format is used by professional designers and is the native file format of Adobe Photoshop. You need Adobe Photoshop to open this file type.

.gif---------------------------------------------- Optional Transparent Extras: Gif (RGB Color) 72 dpi. Gif files do not resize well at all. For us to supply you with a transparent gif file you need to tell us the size you need. Otherwise if you try to resize it yourself the results will generally be very poor. Gif files are not the best quality file format and often suffer from pixalation. This is the technical word for "jagged edges", or "bitty-ness". If you want this file format, you can request when you place your order, but please remember to supply the size required.
.png-------------------------------------------------------------------------------- PNG (RGB Color) 72 dpi. PNG files are a fairly new arrival on the scene. It is a website file format supported now by most web browsers. The beauty of this format is that the quality of finish is usually high. The PNG file format also resizes much better than Gif files. Request this format when you place your order should you require it.
