The scale is about 1.5 times of your actual output. Whether the color is black and white depends on your logo. The resolution is only 150dpi. If it is too low, you may lose details.
(Although adobe's graphic design masters all suggest this, some people don't like to do so, but directly face the manuscript on the computer or model it by memorizing it. In my opinion, this method is inefficient and will distract you from other production details. But for highly trained designers, it can also be exercised and controlled by multi-process divergent thinking)
2. according to your scanned manuscript, trim the shape of the logo and fill it up.
Usually making a standard logo requires vector shape, so it needs vectorization. Commonly used softwares include streamLine of adobe and vector tracing tools attached to AI, FH and CD. You can also do it directly in vector software.
(Sometimes I personally think it is more convenient to use PS selection to convert paths and then save them in vector tools for pruning. Especially for content with hand-drawn or calligraphy parts)
3. Combine your LOGO components reasonably to prepare for future use and output.
I often meet some designers who make such mistakes when making LOGO: the parts that should be merged in graphic parts are incomplete, or the group components don't grasp the rules. This will cause a lot of unnecessary trouble in the application.
Usually, parts of the same color need to be combined together, so that they will not be missed when modifying the color;
Blank parts of components should not be simply covered with white or background color;
Especially when there is a contour line setting, it is suggested that it is best to convert the contour line into a shape object to avoid unexpected changes caused by conversion between different operating platforms and different vector files.
When making large outdoor signs, there are some differences between the shape details and those used in plane printing, including the signs used for making metal nameplates. Due to different processes, there are also many minor adjustments in the details.
To put it simply, as far as the production of printed logo suits is concerned, the details of LOGO smaller than 25mm square should enlarge and exaggerate the original LOGO. For example, the well-known Minolta camera logo, its small logo in the application, expanded the center of the thin line interval. Its purpose is to make signs of different sizes keep the same image features in different visual ranges.
