What’s the most important part of a summer party? Good weather! Which is why KOCHAN & PARTNER’s party was all about the weather. The invitation to our “part(l)y cloudy” was a playful take on currents and pressure, light and shadow. The inside text is only legible in direct sunlight – due to UV-sensitive screen printing ink. For a jet-black color another layers of ink was added to the black outside: 80 % cyan for the background and 100 % cyan for the streamlines.
