Logos are an integral part of most designs and must sit and blend well with the surroundings.
Often too I see logos with a solid background or logos cut from existing backgrounds. To make matters worse these logos will be JPEG.
Whoever designs your logo must give you these;
Transparent PNG Logos
Your logo must have a transparent background and the PNG format best supports alpha channels (transparency).
Transparent logos can blend well on any contrasting surface. Usually it’s wise to use a transparent logo and place it on any background that you create.
If the background does not contrast with the logo you can place a shape filled with a contrasting colour
Make sure whoever designs your logo gives you a transparent version of it and must also be trimmed and cropped.
Flat/ Monochrome Logos
Along with a full colour a logo must have flat colour variants of itself like black or white. These colours can blend well on most surfaces/ backgrounds or designs
Your logo designer must give you these as well.
Besides black or white, you can have other flat colours as well. For example, if your logo is flat blue you can use the Hue rotate filter to change colours of it. This also help the logo to match the surrounding colours.
NB: Don’t use logos that already have styles on them like shadows, fancy 3D and filters(unless you know what you’re doing). When designing flyers, posters, banners these effects may obscure the design. Instead use flat logos and apply styles in whatever DESIGN TOOL you will use.
PDF/ SVG/ EPS
These versions of a logo are mostly suited when you want your logo to be printed.
They are called vectors and offer the sharpest quality because they use a series of mathematical calculations to render lines. The other formats above are called rasters and use tiny dots of colours called pixels to render an image. When these images are zoomed their quality is reduced and look pixelated.
In addition, PDFs can allow someone re-edit and modify the logo using Vector softwares and produce another variant.
Wrapping Up
Additionally, your designer must give you the right logo sizes. Typically for PNG logos you may need a small and a large high resolution size.
Depending on where you want to use the logos he can also give you other size variants or icons of the logo.
When it comes to delivery make sure you’re given the original files or in a ZIP file so that when unpacked the quality remains the same.
Don’t send the image files over Whatsapp as it can reduce the quality and or remove transparency.
Always use the original logo when designing be it a flyer, poster or anything
