Fireworks do not pull the map to achieve the logo anti-white effect of the example teaching

We often need to deal with the customer's corporate identity when we do the website. If your site has a different color background, you need to the customer to provide the identification of white processing, if the customer only provide a white background JPG image files should do?

Usually we will think of pull to the bottom to solve, however, according to a compressed dot matrix, the logo itself is not pure color, more details are difficult to use to pull the map to show. The most obvious example is the registration mark in the corner of the logo. If the use of simple deduction techniques, the word will appear very unnatural.

According to some previous work experience, I found a simple and practical enterprise logo in the fireworks environment to share with you, you can eliminate the trouble of digging the map.

Let's take a look at the examples below. First, set a color background for a complex point, as shown in the following figure:

Borrow a logo from Adidas (Adidas) to the scene as an example.

In the Properties panel, the real-time effects filter, adjust color, hue/saturation. Turn the picture into a black-and-white grayscale.

Adjust the layer mode to the screen.

Continue our real-time effect filter, plus color fill, whatever color you choose, transparency 100%, blending mode to reverse.

Then we can see the effect is out. But the logo is a little translucent, because the color of the logo itself is not dark enough.

If the logo itself is pure black, our work will be over. But now the situation needs to be improved.

Continue the live effects filter, add brightness/contrast, and adjust the contrast to 64.

This contrast value is not fixed, with the original logo color brightness adjusted, the adjustment of excessive words will cause the details of sawtooth.

In this instance, 64 is the most appropriate contrast setting.

A perfect anti-white logo is done.

Let's take a look at the effect of other logos against white.

This method is suitable for the logo with simple color and dim brightness.

Multi-color identification is more difficult to serve, especially in the logo is bright enough elements, the effect of Mingdolian will make the elements of transparent effect.

It's acceptable to be like this.
